# Sheep Barn Lambing Area: Design for Efficiency and Hygiene ## Key Takeaways - **Dedicated Zoning and One-Way Flow:** Implement distinct zones for dry ewes, lambing, individual pens (jugs), and mothering pens, facilitating a unidirectional movement of ewes to minimize disease transmission and stress. - **Pen Sizing and Hygiene:** Utilize individual lambing pens (jugs) of 4x4 to 5x6 feet, ensuring sufficient space for ewes and newborns, with solid lower walls to prevent lamb escape and nose-to-nose contact, thereby reducing disease spread. - **Ventilation and Ammonia Control:** Maintain a minimum of 4-6 air exchanges per hour, particularly in winter, to keep ammonia levels below 10 parts per million and prevent moisture buildup, which exacerbates respiratory diseases and navel infections. - **Disinfection and Bedding Protocols:** Thoroughly disinfect pens between lambing batches by removing all bedding, washing surfaces with hot soapy water, rinsing, and applying an approved disinfectant, followed by a minimum of 4-6 inches of clean, absorbent bedding like straw. - **Navel Care and Colostrum Management:** Immediately dip newborn lamb navels in 7% iodine solution twice within the first 4 hours and ensure lambs receive colostrum within 6-12 hours of birth to confer passive immunity against neonatal diseases like watery mouth and joint ill. --- Lambing season is the most intense period on most sheep operations. The physical layout of your lambing area directly affects how many lambs survive, how quickly ewes recover, and how much labor you pour into each birth. This guide covers how to design a sheep barn lambing area that supports clean births, easy observation, and efficient handling. It is written for sheep producers who manage their own facilities, from small farm flocks to larger commercial operations, and for anyone planning a new barn or renovating an existing one. ## At a Glance - **Separate the lambing area from the main barn.** Use a dedicated space for ewes that are close to lambing, actively lambing, and mothering up with newborns. - **Plan for at least 16 to 20 square feet per ewe** in the main lambing pen and 16 to 25 square feet per ewe in group pens. - **Use individual lambing pens (jugs) that are 4 by 4 feet to 5 by 6 feet.** Larger ewes need the bigger size. Each jug needs a water bucket, feed pan, and clean bedding. - **Design for a one-way flow.** Move ewes from the holding area to the lambing pen, then to mothering pens, then to the main flock. This prevents disease spread and reduces stress. - **Ventilation is critical.** Aim for 4 to 6 air exchanges per hour in winter without creating drafts at lamb height. Ammonia levels should stay below 10 parts per million. - **Disinfect between batches.** Remove all bedding, wash surfaces with hot soapy water, rinse, and apply a disinfectant approved for livestock facilities. - **Have a clean, dry, draft-free corner for weak lambs.** A warming box or heat lamp area can save chilled lambs, but it must be separate from the main traffic flow. - **Keep records at the pen.** A simple whiteboard or waterproof notebook at the lambing area entrance helps track which ewe lambed, when, and any treatments given. ## Why the Lambing Area Layout Matters The sheep barn lambing area is where you manage the highest risk period in the ewe production cycle. A poorly designed space creates problems that show up as dead lambs, sick ewes, and exhausted shepherds. The design determines how easily you can observe ewes, intervene in difficult births, clean pens, and prevent disease transmission between animals. Sheep are prey animals. A ewe giving birth needs to feel secure enough to labor normally. Constant disturbance, poor footing, or overcrowding can stall labor and lead to dystocia, or difficult birth. The barn layout should let you observe without entering the pen, and let the ewe isolate herself from the flock when she is ready to give birth. The hygiene of the lambing area is the single most controllable factor in reducing neonatal lamb losses. The main causes of lamb death in the first week are starvation, exposure, and disease, particularly watery mouth, joint ill, and navel infections. All of these are influenced by how clean and dry the lambing environment is. A ewe that lambs onto wet, manure-packed bedding gives her newborn a mouthful of bacteria with the first suckle. That same bedding contaminates the navel and creates an entry point for infection. The design also affects your labor efficiency. A well planned sheep barn lambing area lets one person check 50 ewes in a few minutes, spot a ewe in active labor, and intervene without chasing animals around the barn. Poor sight lines, narrow alleys, and poorly placed gates turn every check into a wrestling match. Over a six week lambing season, that wasted time adds up to hundreds of hours. ## Key Design Principles for a Sheep Barn Lambing Area ### Zoning and Traffic Flow Divide the lambing barn into distinct zones. Each zone serves one purpose and animals move through them in a single direction. The basic zones are: 1. **Dry ewe holding area.** This is where pregnant ewes wait before they move into the lambing area. It should be close to the lambing barn but separate from it. Ewes that are not yet showing signs of labor stay here. 2. **Lambing area.** This is the main sheep barn lambing area where ewes give birth. It can be a single large pen or a series of smaller pens. Some producers use this as a group lambing space, others use it as a staging area before moving ewes into individual jugs. 3. **Individual lambing pens (jugs).** These are small, individual pens for a ewe and her newborns. The ewe stays here for 24 to 48 hours after birth so she bonds with her lambs and you can monitor them closely. 4. **Mothering pens.** These are small group pens where 3 to 5 ewes and their lambs are grouped together after leaving the jugs. This allows the lambs to socialize and the ewes to adjust to being in a group again. 5. **Recovery or hospital area.** This is a separate, easily cleaned space for sick ewes, orphan lambs, or ewes with mastitis. It should be physically separated from the healthy lambing flow. The one-way flow principle means a ewe never moves backward through the system. She comes in from the holding area, moves to a jug, then to a mothering pen, then out to the main flock. This prevents a ewe that is incubating a disease from contaminating ewes that have not yet lambed. ### Pen Sizing and Dimensions Pen size depends on the breed and mature weight of your ewes. A 200 pound ewe needs more space than a 120 pound ewe. Use these as minimum guidelines: | Pen Type | Minimum Size per Ewe | Notes | |---|---|---| | Group lambing pen | 16 to 20 square feet | For ewes in early labor or waiting | | Individual jug | 4 x 4 feet (16 sq ft) to 5 x 6 feet (30 sq ft) | Small breeds can use 4 x 4, large breeds need 5 x 6 | | Mothering pen | 20 to 25 square feet per ewe | For 3 to 5 ewes with lambs | | Hospital pen | 40 to 50 square feet per ewe | Extra space for sick animals | The jug size is critical. A jug that is too small makes it hard for the ewe to lie down and get up, which can lead to problems with the lamb finding the udder. A jug that is too large wastes bedding and makes it harder for the ewe and lambs to find each other. The jug should be just large enough for the ewe to turn around comfortably and for you to enter to assist if needed. Pen walls for jugs should be solid on the bottom half and slatted or open on the top half. This lets air move through while preventing drafts at floor level. It also lets the ewe see other sheep, which keeps her calmer. Solid lower panels prevent lambs from crawling into neighboring pens and prevent nose to nose contact between ewes, which reduces disease spread. ### Flooring and Drainage The floor of the sheep barn lambing area must be easy to clean and dry quickly. Concrete is the most common choice because it is durable, easy to disinfect, and does not absorb urine. The downside is that it is hard on the ewes' feet and can be slippery. Score or roughen new concrete to provide traction. If you have smooth concrete, apply a non slip coating or use rubber mats in high traffic areas. Dirt floors are acceptable in some situations but they are impossible to fully disinfect. If you use a dirt floor, you must remove the top layer of contaminated soil between lambing seasons and replace it with clean fill. This is labor intensive and rarely done well. For most operations, concrete with good drainage is the better choice. The floor should slope slightly, about 1 to 2 percent, toward a drainage channel. This lets urine and wash water flow away from the pens rather than pooling. The drainage channel should lead to a septic system or a properly designed manure storage area, not directly to a waterway. Check your local regulations for manure and wash water disposal requirements. ### Bedding Management Bedding is your first line of defense against disease in the sheep barn lambing area. The goal is to keep the ewe and lambs dry and clean. Use a generous layer of absorbent bedding, at least 4 to 6 inches deep, and add fresh bedding daily. Good bedding options include: - **Straw.** This is the best all around choice. Wheat straw is more absorbent than barley or oat straw. It provides good footing and is comfortable for the ewe to lie on. - **Wood shavings.** These are absorbent and easy to handle. Avoid fine sawdust because it can get into the lambs' nostrils and cause respiratory irritation. Cedar shavings can be irritating to some animals. - **Chopped paper.** This works in a pinch but is less absorbent than straw and can blow around the barn. - **Sand.** This is used in some dairy operations but is not practical for lambing because it is heavy to handle and can pack into the ewe's fleece. Do not use whole corn stalks or other coarse materials that can poke the ewe or lamb. Do not use moldy or dusty bedding. Mold spores cause respiratory problems in both ewes and lambs. The bedding management schedule depends on the stocking density and the time of year. In cold weather, ewes will pack more bedding into their fleeces and you will need to add more. The key is to keep a dry layer on top. When the bedding becomes wet or manure packed, remove it and replace with fresh material. In a busy lambing area, this may mean cleaning some pens twice daily. ### Ventilation and Temperature Ventilation is the most misunderstood aspect of sheep barn lambing area design. Many producers close the barn up tight to keep the ewes warm, then wonder why the lambs get pneumonia. The problem is not cold, it is moisture and ammonia. A ewe and her lambs produce a large amount of moisture through respiration and urine. In a closed barn, this moisture condenses on the walls and ceiling and drips onto the bedding. Wet bedding breeds bacteria and increases the risk of navel infections and pneumonia. Ammonia from urine buildup irritates the lambs' respiratory tracts and makes them more susceptible to disease. The goal is to provide continuous ventilation without creating drafts at lamb height. This means air moves through the barn at a rate that removes moisture and ammonia but does not blow directly on the animals. A good rule of thumb is 4 to 6 air exchanges per hour in winter and more in summer. Design the ventilation system with these features: - **Ridge vent.** This runs along the peak of the roof and allows warm, moist air to escape naturally. - **Eave inlets.** These are openings under the eaves that let fresh air enter. They should be adjustable so you can control the amount of incoming air. - **Side wall vents.** These can be opened in mild weather to increase airflow. - **Exhaust fans.** In larger barns, fans are needed to move air in summer and to supplement natural ventilation in winter. The key is to keep air moving at the ewe's head level while protecting the lambs at floor level. Solid pen partitions on the lower half of the jug walls provide this protection. A ewe can tolerate temperatures well below freezing if she is dry and out of the wind. The lambs are more vulnerable, but they stay close to the ewe and benefit from her body heat. Monitor ammonia levels in the barn. If your eyes water when you walk in, the ammonia is too high. Open the vents or increase airflow. Ammonia levels should stay below 10 parts per million. Simple ammonia test strips are available at farm supply stores and are worth the small investment. ### Lighting Good lighting in the sheep barn lambing area is essential for observation and for assisting with difficult births. You need to see what you are doing when you are helping a ewe deliver a lamb. Poor lighting leads to missed problems and unsafe interventions. Install bright, even lighting over the lambing area. LED lights are energy efficient and provide good color rendering. You want lights that show the true color of the ewe and lamb so you can spot signs of distress, such as pale mucous membranes or blue tinged tongues. Place lights so they do not shine directly into the ewes' eyes. Bright light directed at a laboring ewe can stress her and slow the birth process. Aim lights at the floor and the working area, not at the ewe's face. Use a timer or dimmer to create a day night cycle in the barn. Continuous bright light stresses sheep and disrupts their natural behavior. A simple timer that provides 12 to 14 hours of light and 10 to 12 hours of darkness works well. ### Water and Feed Access Every jug and pen in the sheep barn lambing area needs access to fresh, clean water. A ewe that has just lambed is thirsty and needs to drink to produce colostrum and milk. Dehydration is a common cause of poor milk production and weak lambs. In individual jugs, use a bucket that hangs on the wall or sits in a corner bracket. The bucket should be at a height that the ewe can reach easily but the lambs cannot climb into. A 2 to 3 gallon bucket is the right size for a jug. Check every bucket at every feeding and refill as needed. A ewe can drink 2 to 3 gallons of water per day, more if she is producing a lot of milk. In group pens, use a water trough or automatic waterer. The trough should be large enough that all ewes in the pen can drink at the same time. A rule of thumb is 2 linear feet of trough space per ewe. Automatic waterers save labor but they must be checked daily to make sure they are working and not frozen in winter. Feed access is equally important. A ewe that lambed yesterday needs to start eating to produce energy for milk production. Offer good quality hay or a balanced ration in the jug. Use a feed pan or hay rack that the lambs cannot access. Lambs will start nibbling on solid feed at about 2 weeks of age, and they need their own creep feed area in the mothering pens. ### Handling and Working Areas The sheep barn lambing area needs a handling system that lets you catch and restrain ewes safely. This includes: - **A catch pen.** This is a small pen where you can isolate a ewe for examination or treatment. It should be 4 by 6 feet or large enough for one ewe and a person. - **A race or chute.** This is a narrow passage that holds a ewe still while you examine her. It should be 18 to 24 inches wide and 6 to 8 feet long, with a gate at both ends. - **A head gate or squeeze.** This restrains the ewe's head so you can treat her safely. It is essential for procedures like checking a ewe's eyes, mouth, or udder. Place the handling area at the edge of the lambing area, not in the middle of the traffic flow. You do not want to move a ewe through the entire barn to treat her. The handling area should be close to the jugs and have good lighting and easy access to your supplies. The handling area also needs a clean, dry place for your equipment. A shelf or cabinet near the handling area should hold obstetrical lubricant, gloves, iodine for navels, a lamb puller, and other supplies. Keep everything organized so you can find it quickly in an emergency. ## Step by Step: Setting Up Your Lambing Area ### Step 1: Choose the Location If you are building a new sheep barn lambing area, choose a location that is: - Close to the main sheep barn or pasture so ewes can be moved easily - Protected from prevailing winter winds - On well drained ground - Accessible to your truck and trailer for deliveries and [emergency vet](/knowledge/veterinary-medicine/emergency-care/emergency-vet) visits - Near a water supply and electricity If you are renovating an existing barn, consider how the lambing area will fit into the existing layout. You may need to move interior walls, add insulation, or improve the floor. The cost of renovation is often less than building new, but make sure the existing structure can be adapted to meet your needs. ### Step 2: Calculate Your Space Needs Determine how many ewes you will lamb at one time. This is not necessarily your total flock size. If you lamb in groups, you might have 50 ewes lambing in a six week period, with 10 to 15 lambing in any given week. Your lambing area needs to hold the peak number of ewes, not the total flock. Here is a simple calculation: 1. **Estimate peak lambing load.** Divide your total lambing period by the number of ewes. If you have 100 ewes lambing over 6 weeks, you average about 17 ewes per week. Plan for 50 percent above the average to account for peaks, so about 25 ewes at once. 2. **Calculate jug space.** You need one jug for every 8 to 10 ewes in the lambing group. For 25 ewes, you need 3 to 4 jugs. Ewes stay in jugs for 24 to 48 hours, so jugs turn over quickly. 3. **Calculate group pen space.** The remaining ewes are in group pens. For 25 ewes, you need about 500 square feet of group pen space. 4. **Add mothering pen space.** You need enough mothering pens to hold ewes and lambs for 3 to 5 days after they leave the jugs. For 25 ewes, plan for 3 to 5 mothering pens of 100 to 125 square feet each. ### Step 3: Build the Pens Use sturdy, portable panels or fixed wooden walls for the pens. Portable panels are more flexible and let you reconfigure the space for different group sizes. Fixed walls are more durable and provide better draft protection. For jug walls, use panels that are 3 to 4 feet high. The bottom 18 to 24 inches should be solid, the top can be open or slatted. Use a gate or a drop down panel for access. The gate should open into the jug so you can close it behind you when you enter. For group pens, use panels that are 4 feet high. This is tall enough to prevent ewes from jumping over but low enough that you can reach over to catch an animal. The bottom of the panels should be solid to prevent drafts and to keep lambs inside. Attach the panels securely to the floor or to each other. A ewe in labor can push hard against a panel, and a panel that falls over creates chaos. Use brackets, clips, or chains to secure all panels. ### Step 4: Install Water and Feed Systems Run water lines to the lambing area before you set up the pens. You need a water source that does not freeze in winter. Install frost proof hydrants or heat tape on exposed pipes. Place the water source so you can reach all pens with a hose. For individual jugs, set up a bucket system. Each jug needs a bucket bracket or hanger. Position the bracket so the bucket is against a wall, out of the way of the ewe's movements. The bucket should be easy to remove for cleaning and refilling. For group pens, install a trough or automatic waterer. Place it along a wall so it does not take up pen space. Make sure the waterer is at a height that lambs cannot climb into it. Some producers build a small platform or guard around the waterer to keep lambs out. Set up feed storage near the lambing area. You need a clean, dry place to store hay and grain. A feed room attached to the barn is ideal. If you store feed in the barn, keep it in covered containers to prevent contamination from dust and manure. ### Step 5: Set Up Lighting and Electrical Outlets Install the lighting system before you put animals in the barn. You need: - Overhead lights over the main lambing area - Individual work lights over the jugs - A light over the handling area - A light near the entrance for nighttime checks Use weatherproof outlets throughout the barn. You need outlets for: - Heat lamps (use ceramic sockets and secure the lamps so they cannot fall) - Warming boxes - Fans in summer - A radio or alarm system if you use one Install all electrical systems according to local codes. Use ground fault circuit interrupters on all outlets near water. Protect all wiring from rodents and from the animals themselves. ### Step 6: Prepare the Bedding Before lambing starts, lay a deep, even layer of clean bedding over the entire floor of the lambing area. Use 6 to 8 inches of straw or shavings. This initial layer absorbs moisture and provides a clean surface for the ewes. Have a supply of extra bedding stored nearby. You will use more bedding than you expect. A good rule is to have one bale of straw for every 2 to 3 ewes for the entire lambing season. Store the bedding in a dry area, not in the lambing barn where it can absorb moisture and mold. Set up a bedding storage area near the lambing pens. A wheelbarrow or feed cart stocked with bedding makes it easy to add fresh material to pens throughout the day. ### Step 7: Stock the Supplies Before the first ewe lambs, gather all the supplies you will need. Keep them in a clean, organized cabinet or shelf near the handling area. Essential supplies include: - **Obstetrical lubricant.** Use a water based lubricant for vaginal exams and assisted deliveries. - **Disposable gloves.** Use shoulder length gloves for vaginal exams. Have a box in the lambing area and in your pocket. - **Iodine solution (7 percent).** This is for dipping navels of newborn lambs. - **A lamb puller.** This is a tool for assisting with difficult births. Use it only if you are trained to use it. Improper use can injure the ewe and lamb. - **Nursing bottles and nipples.** For orphan lambs or lambs that need supplemental feeding. - **Colostrum replacer.** This is essential for lambs that do not get colostrum from their mothers. Store it in a cool, dry place and check the expiration date. - **Heat lamps or a warming box.** For chilled lambs. - **Scale.** A spring scale or digital scale for weighing lambs. - **Ear tags and tagging equipment.** - **Record keeping supplies.** A waterproof notebook, pen, and whiteboard. - **First aid supplies.** Antiseptic spray, bandage material, and a thermometer. ### Step 8: Set Up Records Set up a record keeping system before lambing starts. The system should be simple enough to use in the middle of the night when you are tired and in a hurry. Use a whiteboard at the entrance to the lambing area. Write the date, the ewe number, the number of lambs born, and any treatments given. This board gives you and anyone else working in the barn a quick overview of what has happened. Keep a detailed notebook or record sheet for each ewe. Record: - Ewe identification number - Date and time of lambing - Number of lambs born and their sex - Birth weights - Any assistance needed during birth - Any treatments given to the ewe or lambs - Any problems observed, such as retained placenta or mastitis Write down the ewe's lambing history. This information helps you make decisions about which ewes to keep and which to cull. A ewe that consistently has difficult births or poor mothering ability is a candidate for culling. ## Common Mistakes in Sheep Barn Lambing Area Design ### Overcrowding the Lambing Area The most common mistake is trying to lamb too many ewes in too small a space. Overcrowding leads to: - Increased disease transmission - More difficult births because ewes cannot find a quiet spot - More lambs being stepped on or laid on by other ewes - Higher stress levels, which reduce milk production and mothering ability - More labor required to keep the area clean Resist the temptation to push more ewes into the lambing area than the space can hold. It is better to lamb in smaller groups with a clean, well managed area than to have a crowded, dirty barn. ### Poor Ventilation The second most common mistake is closing the barn up too tight to save heat. This creates a warm, moist, ammonia filled environment that is perfect for bacterial growth and respiratory disease. Remember that sheep are more cold tolerant than heat tolerant. A ewe with a dry fleece can handle temperatures well below freezing. The lambs stay close to the ewe and are protected by her body heat. The bigger risk is dampness and drafts, not cold. Monitor the temperature and humidity in the barn. If condensation is forming on the walls and ceiling, you need more ventilation. If the air smells strongly of ammonia, you need more ventilation. If the lambs are shivering and huddling, you may need to provide a heat source or reduce drafts. ### Inadequate Drainage A lambing area without proper drainage becomes a swamp. Water from urine and cleaning pools on the floor, saturates the bedding, and creates a breeding ground for bacteria. If your barn floor does not have proper drainage, you have several options: - **Install a drainage channel.** Cut a channel across the floor that slopes to a collection point. Cover it with a grate to prevent injury. - **Use a raised floor.** Build a slatted or raised floor over the existing floor. This is expensive but effective. - **Use deep bedding.** If you cannot fix the drainage, use a deep bedding pack and add fresh material regularly. Remove the entire pack between lambing seasons. ### Placing the Handling Area in the Wrong Location The handling area must be close to the lambing pens but not in the main traffic flow. If you have to move a ewe through the entire barn to treat her, you disturb other ewes and create stress. Place the handling area at the edge of the lambing area, near the entrance. This lets you bring a sick ewe in for treatment without moving her past healthy animals. It also keeps the handling area out of the way of daily chores. ### Not Having a Hospital Area Every lambing barn needs a separate area for sick animals. This is not optional. A ewe with mastitis, a lamb with joint ill, or an orphan lamb needs to be isolated from the healthy flock. The hospital area should be: - Physically separate from the lambing area, preferably in a different room or building - Easy to clean and disinfect - Well ventilated - Equipped with its own water and feed supplies Use the hospital area for any animal that might be contagious. Do not move a sick animal into a jug in the main lambing area. This risks infecting every other ewe and lamb in the barn. ## Monitoring and Recordkeeping During Lambing ### How Often to Check the Flock During peak lambing, check the flock every 2 to 4 hours around the clock. This is exhausting but necessary. Most lambing problems need intervention within an hour or two to save the lamb and the ewe. If you have a small flock and lamb over a short period, you may be able to manage with checks every 4 hours. For larger flocks, consider a scheduled rotation with family members or employees. The key is to catch problems early, when intervention is most likely to succeed. During each check, look for: - Ewes that are separated from the group and showing signs of labor - Ewes that have been in labor for more than 30 to 60 minutes without producing a lamb - Lambs that are weak, chilled, or not nursing - Ewes with signs of mastitis, such as a hot, swollen udder - Lambs with signs of disease, such as scours or joint ill ### What to Record Keep accurate records for every ewe and lamb. This information is valuable for making management decisions throughout the year. Record for each ewe: - Identification number - Date and time of lambing - Number of lambs born - Ease of lambing (unassisted, easy pull, hard pull, cesarean) - Any problems such as retained placenta, metritis, or mastitis - Any treatments given Record for each lamb: - Identification number - Birth weight - Sex - Single, twin, or triplet - Any problems such as weakness, disease, or injury Review these records at the end of lambing season. Look for patterns. Are certain ewes consistently having difficult births? Are certain bloodlines producing weak lambs? Use this information to make culling and breeding decisions. ### When to Intervene Knowing when to intervene in a birth is one of the most important skills in sheep management. Intervene too early and you may cause more harm than good. Intervene too late and you may lose the lamb and the ewe. Call for veterinary help or intervene yourself if: - A ewe has been in active labor for more than 30 to 60 minutes without producing a lamb - A ewe has been straining for 30 minutes or more with no progress - You see a nose and feet but no progress for 15 to 20 minutes - You see only a head or only feet, which indicates a malpresentation - The ewe shows signs of distress, such as rapid breathing, weakness, or a blue tinge to the mucous membranes - The water bag has broken and no lamb appears within 30 to 60 minutes If you are not trained in obstetrical procedures, call a veterinarian or an experienced shepherd for help. Improper intervention can cause serious injury to the ewe and the lamb. ## Decision Thresholds for the Lambing Area ### When to Move a Ewe to the Lambing Area Move a ewe to the lambing area when she shows signs that lambing is imminent. These signs include: - The udder is full and the teats are waxed - The ligaments around the tail head are relaxed - The ewe is restless, pawing the ground, and lying down and getting up frequently - The ewe is isolating herself from the flock - The vulva is swollen and there is a clear mucus discharge Do not move a ewe too early. Moving a ewe that is not close to lambing causes stress and may delay the birth. Move her when she is clearly in the early stages of labor. ### When to Move a Ewe and Lambs to a Mothering Pen Move a ewe and her lambs out of the jug and into a mothering pen when: - The ewe has passed the placenta - The lambs are nursing well and the ewe is mothering them normally - The lambs are strong and active - The ewe has been in the jug for at least 24 hours Do not move them too early. The first 24 hours are critical for bonding and for the lamb to get colostrum. Moving the ewe and lambs too soon can disrupt the bonding process and lead to a ewe that rejects her lambs. ### When to Move a Ewe and Lambs to the Main Flock Move a ewe and lambs to the main flock when: - The lambs are at least 3 to 5 days old - The lambs are nursing well and gaining weight - The ewe has no signs of infection or mastitis - The weather is suitable for the lambs to be outside Do not move them to the main flock too early. Lambs need time to develop their immune systems and to learn to follow their mothers. A ewe that is moved to the main flock with a very young lamb may lose the lamb in the crowd. ### When to Call a Veterinarian Call a veterinarian immediately if: - A ewe has been in labor for more than 2 hours without producing a lamb - You see a malpresentation that you cannot correct - A ewe has a prolapsed uterus or vagina - A ewe is showing signs of toxemia or pregnancy disease - A ewe has a high fever (above 104 degrees Fahrenheit) after lambing - A lamb is severely chilled and does not respond to warming - A lamb is very weak and will not nurse Do not wait to call for help. The longer you wait, the more likely you are to lose the animal. A veterinarian can often save a ewe or lamb that you might lose on your own. ## Hygiene Protocols for the Sheep Barn Lambing Area ### Daily Cleaning Routine A daily cleaning routine keeps the sheep barn lambing area clean and reduces disease pressure. The routine should include: 1. **Remove wet and soiled bedding.** Use a fork and wheelbarrow to remove wet spots and manure from each pen. Do this at least once a day, more often in heavily used pens. 2. **Add fresh bedding.** After removing soiled bedding, add fresh, clean bedding to maintain a 4 to 6 inch layer. 3. **Clean water buckets.** Empty, scrub, and refill all water buckets daily. Use hot water and a mild detergent. Rinse thoroughly to remove all soap residue. 4. **Clean feed pans.** Remove uneaten feed and scrub the pans. Refill with fresh feed. 5. **Sweep the aisles.** Keep the walkways clean and free of manure and bedding. This reduces the amount of dirt tracked into the pens. 6. **Check the ventilation.** Adjust vents and fans as needed to maintain good air quality. ### Disinfection Between Batches Disinfect the lambing area between batches of ewes. This is especially important if you had any disease problems in the previous batch. The disinfection process: 1. **Remove all animals.** Move the ewes and lambs to a clean area before you start cleaning. 2. **Remove all bedding.** Strip the pens down to the floor. Remove every bit of bedding and manure. 3. **Clean the surfaces.** Scrub all surfaces with hot water and a detergent. Use a stiff brush to remove dirt and organic matter. Pay special attention to corners and cracks where bacteria can hide. 4. **Rinse thoroughly.** Rinse all surfaces with clean water to remove detergent residue. 5. **Apply disinfectant.** Use a disinfectant approved for livestock facilities. Common choices include chlorhexidine, quaternary ammonium compounds, or a 10 percent bleach solution. Follow the label instructions for dilution and contact time. 6. **Allow to dry.** Let the pens dry completely before adding fresh bedding and bringing in new animals. 7. **Add fresh bedding.** Use a deep layer of clean, dry bedding. ### Navel Care Navel care is one of the most important hygiene practices in the sheep barn lambing area. The navel is a direct entry point for bacteria that cause joint ill and other infections. Immediately after birth: 1. **Dip the navel in 7 percent iodine solution.** Use a small cup or jar. Hold the lamb up so the navel is submerged for a few seconds. 2. **Repeat the dip after 2 to 4 hours.** This second dip catches any bacteria that may have entered after the first dip. 3. **Keep the bedding clean and dry.** A wet, dirty navel is an invitation for infection. Do not cut the navel cord. It will dry and fall off naturally. Cutting it creates an open wound that is more susceptible to infection. ### Colostrum Management Colostrum is the first milk the ewe produces. It contains antibodies that protect the lamb from disease. A lamb that does not get colostrum within the first 6 to 12 hours of life is much more likely to get sick. Ensure that every lamb gets colostrum: 1. **Watch the lamb nurse.** Make sure the lamb finds the udder and nurses within the first 2 hours after birth. 2. **Check the udder.** Make sure the ewe has colostrum and that the teats are open and functional. 3. **Give supplemental colostrum if needed.** If the lamb is weak, chilled, or the ewe has no colostrum, give colostrum replacer. Use a bottle or a stomach tube. Give 10 percent of the lamb's body weight in colostrum within the first 12 hours. 4. **Store extra colostrum.** If you have a ewe with excess colostrum, milk it out and freeze it. Label it with the date and ewe number. Use it for orphan lambs or lambs from ewes with no colostrum. ## Seasonal Considerations ### Winter Lambing Winter lambing puts the most stress on your facilities. The sheep barn lambing area must provide protection from cold, wind, and moisture while maintaining good ventilation. Key considerations for winter: - **Increase bedding depth.** Use 6 to 8 inches of bedding to insulate the lambs from the cold floor. - **Protect from drafts.** Make sure the pens are protected from drafts at lamb height. Use solid panels or bales of straw to block wind. - **Provide a heat source for weak lambs.** A warming box or heat lamp can save a chilled lamb. The box should be 2 by 3 feet and 2 feet high, with a heat lamp or heating pad. The temperature should be around 90 to 95 degrees Fahrenheit for a chilled lamb. - **Check water frequently.** Water can freeze quickly in winter. Check buckets and troughs at every feeding and break ice or refill as needed. - **Have a backup power source.** If you rely on electric heat or waterers, have a generator ready in case of power failure. ### Spring Lambing Spring lambing is easier on facilities but still requires attention to hygiene. The weather is milder, but the barn can become hot and humid, which increases disease pressure. Key considerations for spring: - **Increase ventilation.** Open vents and doors to let in fresh air. Use fans if needed to keep the barn from becoming stuffy. - **Watch for heat stress.** A ewe that is too hot may not eat well, which reduces milk production. Provide shade and plenty of water. - **Manage flies.** Flies breed in manure and soiled bedding. Keep the lambing area clean and use fly control measures as needed. ## Special Situations ### Orphan Lambs Orphan lambs need a special area in the sheep barn lambing area. They are often weak and vulnerable, and they need extra care. Set up a small pen for orphan lambs near the handling area. The pen should be: - Clean and well bedded - Draft free - Equipped with a heat lamp or warming box - Large enough for the lambs to move around and play Feed orphan lambs with a bottle or a lamb milk replacer system. The milk replacer should be mixed according to the label instructions and fed at the correct temperature. Feed orphan lambs 4 to 6 times per day in the first week, then gradually reduce the frequency. ### Ewes with Mastitis Mastitis is an infection of the udder. It is painful for the ewe and can be fatal if not treated promptly. Move a ewe with mastitis to the hospital area immediately. Separate her from her lambs if the infection is severe, because the milk may be harmful to the lambs. Call your veterinarian for treatment recommendations. Keep the hospital pen clean and dry. The ewe needs good bedding and easy access to water and feed. Monitor her temperature and appetite. A ewe with mastitis that does not improve within 24 to 48 hours needs veterinary attention. ### Ewes with Pregnancy Toxemia Pregnancy toxemia, also called ketosis, is a metabolic disorder that affects ewes in late pregnancy. It is caused by an energy deficiency and is more common in ewes carrying twins or triplets. Signs of pregnancy toxemia include: - Depression and lethargy - Loss of appetite - Teeth grinding - Staggering or weakness - In severe cases, recumbency and coma Move a ewe with pregnancy toxemia to the hospital area and call your veterinarian immediately. Treatment may include oral propylene glycol, glucose supplements, and in severe cases, induction of labor or cesarean section. ## Frequently Asked Questions ### How much space does a ewe need in a lambing jug? A ewe needs at least 16 square feet in an individual lambing jug. A 4 by 4 foot jug is the minimum for small breeds. Larger breeds need more space, at least 4 by 5 feet or 4 by 6 feet. The jug should be large enough for the ewe to lie down comfortably and turn around, but small enough that the lamb can easily find the udder and the ewe can bond with her lamb. ### How long should a ewe stay in a lambing jug? A ewe should stay in a lambing jug for at least 24 hours after giving birth. This gives her time to pass the placenta, bond with her lambs, and allow the lambs to nurse colostrum. If the ewe had a difficult birth or the lambs are weak, keep her in the jug for 48 hours. Move her to a mothering pen only when she is mothering well and the lambs are nursing and active. ### What is the best bedding for a sheep barn lambing area? Wheat straw is the best all around bedding for a lambing area. It is absorbent, provides good footing, and is comfortable for the ewe to lie on. Wood shavings are also good, but avoid fine sawdust and cedar shavings. The key is to use a generous layer, at least 4 to 6 inches, and to add fresh bedding daily to keep the surface dry and clean. ### How do I prevent disease in my lambing barn? The most important disease prevention measures are cleanliness and ventilation. Remove wet and soiled bedding daily, add fresh bedding, and keep the barn well ventilated to control moisture and ammonia. Dip every lamb's navel in iodine immediately after birth and again a few hours later. Make sure every lamb gets colostrum within the first 6 to 12 hours of life. Disinfect the entire lambing area between batches of ewes. ### How often should I check ewes during lambing season? During peak lambing, check the flock every 2 to 4 hours around the clock. Most lambing problems need intervention within an hour or two to save the lamb and the ewe. If you have a small flock, you may be able to manage with checks every 4 hours. Schedule your checks so you are present during the times when most births occur, which is often in the early morning and evening. ### What should I do if a ewe is in labor for more than an hour? If a ewe has been in active labor for more than 30 to 60 minutes without producing a lamb, she needs help. First, examine her to determine the position of the lamb. If you are not trained to correct malpresentations, call a veterinarian or an experienced shepherd immediately. Do not pull on the lamb unless you know what you are doing. Improper traction can cause serious injury to the ewe and the lamb. ### How do I warm up a chilled lamb? A chilled lamb needs to be warmed gradually. Place it in a warming box set to 90 to 95 degrees Fahrenheit. If you do not have a warming box, use a heat lamp or a warm water bath. Warm the lamb slowly over 30 to 60 minutes. Do not immerse a lamb in hot water. Once the lamb is warm and dry, give it colostrum and monitor it closely for the next few hours. ### What is the ideal temperature for a lambing barn? The ideal temperature for a lambing barn is between 40 and 55 degrees Fahrenheit. This is comfortable for the ewes and keeps the air dry. The key is not the temperature itself but the ventilation and humidity. A barn that is too warm and humid creates conditions for disease. A barn that is drafty and wet is also a problem. Focus on keeping the barn dry, well ventilated, and free of drafts at lamb height. ## Related Farming Guides This section will be populated with related farming guides and articles.
