Sheep Housing and Shelter: Essential Design Considerations

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-14

Key Takeaways

Ventilation is paramount over warmth: Maintain 4 to 6 air changes per hour in winter to mitigate ammonia buildup and moisture condensation, which are primary drivers of pneumonia and other respiratory diseases, ensuring drafts remain at animal level.
Space allocation is critical for health and productivity: Provide 15-20 sq ft per adult ewe in general housing, 30-40 sq ft in lambing areas, and 16-20 sq ft per lamb in creep areas to minimize stress, competition, and disease transmission.
Site selection and orientation are foundational: Locate buildings on well-drained ground with openings facing away from prevailing winds (typically south or east in North America) to prevent mud accumulation, which exacerbates foot rot and mastitis, and to shield animals from harsh weather.
Lambing pen design directly impacts lamb survival: Individual pens of 4x5 ft or 5x6 ft are recommended to facilitate ewe-lamb bonding and prevent lambs from wandering, with solid sides at least 3 ft high to contain newborns.
Feeding area design minimizes waste and competition: Allocate 3-4 linear feet of feed bunk space per ewe to reduce aggressive competition, which can lead to injuries and nutritional deficiencies, and ensure feeders are designed to prevent feed contamination.
Biosecurity is integrated into facility design: Implement smooth, easily cleanable surfaces, consider footbaths at entrances, and design for logical traffic flow from clean to dirty areas to prevent the introduction and spread of pathogens like Mycoplasma or Pasteurella.

Raising sheep successfully depends on many factors, but the quality of your housing and shelter is among the most important. This guide covers the essential design considerations for sheep barns, lambing sheds, and field shelters. It is written for new and experienced shepherds, small farm operators, and anyone planning to build or improve sheep facilities. You will learn how to assess your climate, plan ventilation, calculate space requirements, design efficient feeding areas, and create a safe environment for lambing. The guide also covers common mistakes, recordkeeping practices, and when to call a veterinarian or extension agent.

Understanding Sheep Housing Requirements

Sheep are hardy animals that can tolerate cold weather better than heat. Their wool provides insulation, but wet and windy conditions create serious health risks. Pneumonia, foot rot, and parasitic infections all become more common when sheep live in damp, crowded, or poorly ventilated spaces. The primary purpose of housing is not to keep sheep warm but to keep them dry and protected from wind.

Sheep housing requirements vary by region, flock size, and production stage. A flock kept for wool production in a dry western climate needs less elaborate housing than a lambing flock in a wet northern state. Before you design any structure, study your local weather patterns. Note the direction of prevailing winter winds, the average rainfall, and the typical temperature range during lambing season. Talk to neighboring farmers about their own facilities and what has worked in your specific area.

The type of sheep you raise also matters. Hair sheep breeds tend to shed their wool and may need more shelter from cold rain. Fine wool breeds have denser fleeces but can still suffer from prolonged wet conditions. Ewes with lambs have higher metabolic demands and need more protection, especially during the first few days after birth. Ram lambs kept together for finishing can be aggressive and require sturdy fencing and feeding equipment.

Your housing plan should match your management style. Some shepherds prefer a system where sheep have constant access to pasture and use shelter only during storms. Others keep ewes in confinement during the lambing season to monitor them closely. Both systems work, but they require different building designs. Decide how much time your sheep will spend inside before you pour concrete or set posts.

Climate Considerations and Site Selection

The single most important decision in sheep housing is where you place the building. A poorly designed barn on a bad site will cause problems for decades. A well-designed barn on a good site makes every other task easier.

Choose a site with good drainage. Low spots that collect water create mud, which leads to foot rot and mastitis. If possible, select a spot with a slight slope so water runs away from the building. The ground should be firm enough to support the building and any heavy equipment you will use for cleaning. If you are building on clay soil, plan for additional gravel or a concrete floor to keep the area dry.

Orient the building to minimize wind exposure. In most of North America, winter winds come from the north and west. Place the main opening of the building to the south or east to keep driving snow and rain out of the interior. A solid wall on the north side protects sheep from the worst weather. If you have flexibility in building placement, use existing trees, hills, or other structures as natural windbreaks.

Consider the distance from your house and other farm buildings. You will visit the sheep barn multiple times daily, especially during lambing season. A barn that is too far away becomes inconvenient, and convenience matters when you are checking ewes at 2 a.m. during a cold snap. At the same time, keep the barn far enough from your house to avoid odor and flies in the summer. A distance of 100 to 200 feet works well for most operations.

Access for trucks and tractors is another key factor. You will need to deliver hay, bedding, and feed. You will also need to remove manure and load animals for market. Plan a driveway wide enough for your largest vehicle and a turning area near the barn. A one-way lane with a turnaround at the barn end is often better than a narrow drive that requires backing out.

Barn Design Fundamentals

The basic sheep barn can take several forms. The most common designs include the open-front shed, the gable-roof barn with center aisle, and the hoop or high tunnel structure. Each has advantages and disadvantages depending on your climate and budget.

The open-front shed is the simplest and most cost-effective design for many flocks. It consists of a roof, a solid back wall, and partial side walls, with the front completely open to the south or east. Sheep can enter and exit freely, which suits a pasture-based system. The open front allows plenty of ventilation while the solid back provides wind protection. These structures work well in mild to moderate climates but can be drafty in very cold regions.

The gable-roof barn with a center aisle is a more substantial building. Sheep are housed in pens on either side of a central feed alley. This design works well for confinement operations and makes feeding and cleaning efficient. The center aisle allows a tractor or skid steer to deliver feed and remove bedding. These barns require more careful ventilation design because the walls are mostly solid and the building is enclosed.

Hoop structures, also called high tunnels, have become popular for sheep housing. They consist of a metal frame covered with a fabric or plastic tarp. The ends can be opened or closed depending on the weather. These buildings are relatively inexpensive, quick to erect, and provide good ventilation when managed properly. The main drawback is that the fabric covering may need replacement every 5 to 10 years, and the interior can become very hot in summer if not properly ventilated.

Whatever design you choose, pay attention to ceiling height. A minimum of 8 feet at the lowest point is recommended for good air movement and easy cleaning. Higher ceilings of 10 to 12 feet provide even better ventilation in summer. In a barn with a loft for hay storage, make sure the support posts do not interfere with pen layouts or cleaning equipment.

The floor of the barn deserves careful thought. Concrete is the most durable and easiest to clean, but it can be hard on sheep legs and requires generous bedding. Packed gravel or dirt floors are cheaper and provide good drainage, but they are harder to sanitize and can become muddy. Slatted or expanded metal floors keep sheep clean and dry but are expensive and can cause foot problems if the slats are not properly spaced. For most small and medium flocks, a well-drained dirt or gravel floor with regular bedding works well.

Ventilation: The Key to Healthy Sheep

Poor ventilation is the most common design flaw in sheep housing. Sheep produce moisture and ammonia through their breath and urine. In a closed barn, this moisture condenses on walls and ceilings, creating a damp environment where pneumonia and other respiratory diseases thrive. Ammonia irritates the lungs and makes sheep more susceptible to infection.

The goal of ventilation is to remove moisture, ammonia, and airborne pathogens while providing fresh air without creating drafts at animal level. In winter, you want to balance heat retention with air exchange. In summer, you want maximum airflow to keep sheep cool.

A simple rule of thumb is to provide 4 to 6 air changes per hour in winter and up to 60 air changes per hour in summer. This does not mean you need mechanical fans in all cases. Natural ventilation can achieve these rates if the building is designed correctly. The key is to have an inlet for fresh air low on the building and an outlet for stale air at the ridge. Warm, moist air rises and exits through the ridge opening, drawing fresh air in through the eaves or side openings.

For a naturally ventilated barn, plan for a ridge opening of at least 2 to 3 inches per 10 feet of building width. The side openings or eaves should provide a similar area of inlet space. In very cold climates, you may need to close some of these openings during extreme weather, but always leave at least some ventilation. A completely sealed barn is dangerous for sheep.

Mechanical ventilation may be necessary for fully enclosed barns or for barns in very hot, humid climates. Exhaust fans mounted in the walls or ridge can move large volumes of air. Intake fans or openings should be positioned so that fresh air flows across the animal zone without creating direct drafts. Thermostats and timers can automate the system, but you must check the system regularly to ensure it is working.

Watch your sheep to assess ventilation quality. If you see condensation on the walls or ceiling, moisture is building up faster than the ventilation can remove it. If your eyes sting or you smell strong ammonia when you enter the barn, ventilation is inadequate. Sheep that are coughing or showing nasal discharge may be reacting to poor air quality. Adjust your ventilation openings and observe the response over several days.

Space Requirements and Pen Layout

Sheep need enough space to move, lie down, and access feed and water without excessive competition. Overcrowding leads to stress, reduced feed intake, and increased disease transmission. Under-crowding wastes space and makes cleaning and management more expensive.

The following space recommendations apply to adult sheep in confinement:

Ewes in dry lot or confinement housing: 15 to 20 square feet per ewe
Ewes in lambing pens: 30 to 40 square feet per ewe
Lambs in creep area: 16 to 20 square feet per lamb
Ram housing: 30 to 40 square feet per ram
Feeder lambs at 60 to 100 pounds: 8 to 12 square feet per lamb

These numbers represent minimums. More space is always better, especially during hot weather or when sheep are heavily pregnant. If you are using an open-front shed with access to pasture, you can reduce the interior space somewhat because sheep will spend time outside. However, all sheep in the group must be able to lie down inside the shelter at the same time during a storm.

Pen layout should follow the natural flow of your management tasks. The feed alley should be accessible for delivering hay and grain. The water source should be positioned so sheep do not have to cross through the feed area to drink. Gates should swing in a way that allows you to move sheep without cornering them or creating bottlenecks.

When designing pens, consider the size of your largest groups. A group of 50 ewes at 18 square feet each needs 900 square feet of pen space. If you divide this into two pens of 25 ewes, you need 450 square feet per pen plus additional space for the dividing wall and gates. Smaller pens make it easier to monitor individual animals and to separate ewes for lambing, but they require more gates and more labor to manage.

The lambing area deserves special attention. This is where you will do your most intensive work. Design the lambing area to be easy to see from the aisle, easy to clean, and easy to access for assisting with difficult births. A central aisle with lambing pens on both sides is a common and effective layout. The aisle should be at least 8 to 10 feet wide to allow for a wheelbarrow or small cart.

Lambing Shed Design

The lambing shed is the most critical housing investment for most sheep operations. A well-designed lambing area improves lamb survival, reduces labor, and makes the lambing season less stressful for both sheep and shepherd.

The lambing shed should be divided into several functional zones. The main holding area holds ewes that have not yet lambed. This area should be dry, well-bedded, and large enough to prevent crowding. The lambing pens are individual pens where ewes give birth and bond with their lambs. The creep area is a small space where lambs can access feed and water without their mothers. The hospital or isolation area holds sick animals or ewes with orphan lambs.

Individual lambing pens should be 4 feet by 5 feet or 5 feet by 6 feet. This is enough space for a ewe to lie down and stand up comfortably while preventing the lambs from wandering too far. The pens should have solid sides at least 3 feet high to prevent lambs from crawling into adjacent pens. The front of the pen should have a gate that opens into the aisle, and the back should have a small opening to the creep area.

Some producers use larger group lambing pens instead of individual pens. These pens hold 5 to 10 ewes that are close to lambing. Group pens require less labor because you do not have to move ewes into individual pens, but they make it harder to monitor individual ewes and to assist with difficult births. A combination system works well: group pens for ewes that are close to lambing and individual pens for ewes that have actually given birth.

The creep area is essential for lamb survival and growth. Lambs need access to creep feed starting at about 2 weeks of age. The creep area should be warm, dry, and protected from drafts. The entrance to the creep should be sized so lambs can pass through easily but ewes cannot follow. An opening about 12 to 14 inches wide and 24 inches high works for most breeds. Place the creep feed and water inside the creep area, and keep the area well-bedded and clean.

The lambing shed should have excellent lighting. You will be working in this area at all hours, including during the night. Install bright LED lights that illuminate the entire space. Consider adding a small heated room or office adjacent to the lambing shed where you can keep records, warm up, and store supplies. This room does not need to be large, but it will make the lambing season much more pleasant.

Temperature management in the lambing shed requires careful attention. Newborn lambs cannot regulate their body temperature well and are vulnerable to chilling. A lambing shed temperature of 40 to 50 degrees Fahrenheit is adequate if the area is dry and draft-free. In very cold climates, you may need to provide heat lamps or other supplemental heat in the lambing pens. Always place heat lamps securely and keep them away from bedding to prevent fires.

Field Shelters and Pasture Housing

Not all sheep need to be housed in a barn year-round. Many producers keep their sheep on pasture and provide only a simple shelter for protection from weather. This system reduces building costs and can improve animal health by reducing exposure to pathogens that build up in confinement.

The simplest field shelter is a three-sided shed with the open side facing away from prevailing winds. The shed should be large enough for all sheep in the pasture to enter at once. A general rule is 10 to 12 square feet of shelter space per ewe. The shelter should be placed on high ground with good drainage. Add a gravel base inside the shelter to keep the area dry and to prevent the shelter from becoming a mud hole.

Portable shelters, such as hoop houses on skids, offer flexibility for rotational grazing systems. These shelters can be moved to fresh pasture as the sheep graze. This distributes manure across the pasture, reduces parasite buildup, and gives the sheep access to shelter wherever they are grazing. Portable shelters are typically 8 to 12 feet wide and 12 to 20 feet long. They are moved with a tractor or ATV, so plan for enough space to maneuver.

In addition to permanent or portable shelters, provide natural windbreaks in pasture systems. Rows of trees, hedgerows, or stacked hay bales can protect sheep from wind and reduce heat loss. These natural windbreaks are often more effective than a building because they slow the wind over a larger area. When planting trees for windbreaks, use species that are hardy in your area and that will not be toxic to sheep if the leaves are eaten.

Water access in pasture systems is a critical design consideration. Sheep need clean, fresh water at all times. In winter, you must prevent water from freezing. Options include heated water tanks, tank heaters, or automatic waterers designed for livestock. Place waterers in a well-drained area to prevent mud. If you are using a portable system, consider how you will move water lines as the sheep move to new pasture.

Feeding Areas and Equipment

The design of feeding areas has a major impact on feed waste, animal health, and labor. Sheep are selective eaters and will waste hay if it is thrown on the ground. Proper feeders save money and reduce the risk of parasite transmission.

Hay feeders come in several styles. The most common is the hay rack or bunk feeder, which holds hay above the ground and allows sheep to pull hay through vertical bars or a mesh. The bars should be spaced 6 to 8 inches apart to allow sheep to access the hay without getting their heads stuck. A solid bottom or a tray beneath the feeder catches hay that falls, allowing sheep to eat it rather than trampling it.

Feed bunk space is a key consideration. The general recommendation is 3 to 4 linear feet of bunk space per ewe when all sheep are eating at once. If you are feeding ewes in groups, this means a group of 25 ewes needs 75 to 100 feet of bunk space. If you are feeding hay that is available all day, sheep can take turns eating, and you can reduce bunk space somewhat. However, competition for feed can lead to injuries and can cause shy ewes to get inadequate nutrition.

For grain feeding, use a trough or feeder that prevents sheep from putting their feet in the feed. A simple design is a trough with a lip or rail that sheep must reach over. The rail should be about 18 to 20 inches high for adult sheep. For lambs, lower the rail or provide a separate lamb feeder in the creep area.

Water systems require the same attention as feeding systems. Sheep drink 1 to 2 gallons of water per day in cool weather and more in hot weather or when lactating. Provide at least 1 to 2 inches of trough space per sheep. The water should be clean and fresh. Clean water troughs regularly to prevent algae and bacterial growth. In winter, check waterers daily to ensure they are not frozen or malfunctioning.

Mineral feeders should be placed where sheep can access them easily but where they will not be contaminated by manure or urine. A covered mineral feeder with a lip to keep out rain is ideal. Place the mineral feeder near the water source, as sheep tend to drink and then seek minerals.

Bedding and Manure Management

Bedding is essential for sheep comfort and health. It provides insulation from cold floors, absorbs moisture, and keeps sheep clean. The type and amount of bedding depend on your climate, floor type, and management system.

Straw is the most common bedding for sheep. It is absorbent, relatively inexpensive, and easy to handle. Barley straw and wheat straw work well. Oat straw is softer but less absorbent. Avoid moldy or dusty straw, as it can cause respiratory problems. Wood shavings also work well and are highly absorbent, but they can be more expensive. Sawdust is less desirable because it packs down and can become wet quickly. Some producers use cornstalks or other crop residues if they are available locally.

The amount of bedding needed depends on the season and the housing system. In a deep-bedded system, you add fresh bedding on top of old bedding, creating a pack that composts over time. This system provides warmth in winter and requires less frequent cleaning. In a scrape-out system, you remove all bedding and manure regularly, typically every few weeks. This system requires more labor but keeps the barn cleaner and reduces ammonia buildup.

A general guide is to use 2 to 4 pounds of straw per ewe per day in winter. Ewes with lambs may need more because the lambs add moisture and the ewe is lying down more. The key is to keep the bedding dry. Wet bedding leads to foot rot, mastitis, and pneumonia. Check the bedding daily and add fresh material to wet spots. If the bedding becomes saturated, remove it and start fresh.

Manure management is a significant consideration in barn design. Plan for how you will remove manure and where you will store it. A concrete apron outside the barn makes cleaning easier and prevents mud. A manure pile or compost site should be located away from the barn and away from any water sources. Composting sheep manure produces a valuable fertilizer, but the compost pile must be managed properly to reduce flies and odor.

Biosecurity and Disease Prevention

The design of your sheep housing can either help or hinder your biosecurity efforts. A well-designed facility makes it easier to clean, disinfect, and control disease. A poorly designed facility makes these tasks difficult and increases the risk of disease outbreaks.

Design all surfaces to be smooth and easy to clean. Concrete floors are easier to sanitize than dirt floors. Wood surfaces are more difficult to clean and can harbor bacteria. Use metal or plastic for gates, feeders, and waterers where possible. If you use wood, seal it with a non-toxic sealant to make it easier to clean.

Plan for footbaths at the entrance to the barn and at the entrance to the lambing area. A footbath is a shallow pan of disinfectant solution that people step through to disinfect their boots. This simple measure reduces the spread of disease between groups of sheep and between farms. Place the footbath where it will not freeze in winter and where it is protected from rain.

The isolation area is a critical part of biosecurity. Any new animal entering your flock should be isolated for at least 30 days. The isolation area should be separate from the main barn, preferably in a different building or at least in a separate room with its own ventilation. You should have separate equipment for the isolation area, including boots, feed buckets, and grooming tools. If you cannot provide a separate building, use the most remote pen in your barn and work with isolation animals last each day.

Traffic flow is another design consideration. Arrange the barn so that the flow of people and equipment moves from clean areas to dirty areas. For example, the feed storage should be at the clean end of the barn, and the manure removal should be at the dirty end. This prevents contamination of feed and clean bedding with manure and pathogens.

Common Design Mistakes

Many sheep housing problems are predictable and preventable. Here are the most common design mistakes and how to avoid them.

Building too much space is rarely a problem, but building too little is common. Producers often underestimate the space needed for lambing pens, feed storage, and equipment. Add 20 percent to your initial space estimate to account for unexpected needs. You will fill the space eventually, and having extra room makes management easier.

Inadequate ventilation is the most serious mistake. Producers often close up the barn to keep sheep warm, creating a damp, ammonia-filled environment. The result is pneumonia and other respiratory diseases. Remember that sheep are more tolerant of cold than of dampness and poor air quality. Always err on the side of more ventilation rather than less.

Poor drainage around the barn creates mud. Mud leads to foot rot, mastitis, and a host of other problems. The area around the barn entrance should be paved or covered with gravel. The barn floor should be higher than the surrounding ground so water does not flow into the building. If you are building on a slope, direct runoff away from the barn with swales or drainage ditches.

Using the wrong materials can create long-term problems. Wood that is not treated will rot quickly in a sheep barn. Metal that rusts will need replacement. Choose materials that can withstand moisture, ammonia, and the wear of daily use. Galvanized metal, treated lumber, and concrete are the most durable choices for sheep housing.

Forgetting about the human working environment is another common mistake. A barn that is dark, cramped, or difficult to clean will be neglected. Install good lighting, provide adequate aisle space, and design for easy cleaning. A comfortable working environment makes you more likely to do the necessary daily checks and cleaning that keep sheep healthy.

Monitoring and Recordkeeping

Good recordkeeping helps you track the performance of your housing system and identify problems early. You do not need an elaborate system, but you should record key information regularly.

Daily observations are the foundation of good management. Walk through the barn at least once a day, preferably twice during lambing season. Look for signs of respiratory distress, such as coughing, nasal discharge, or rapid breathing. Check for lameness, which may indicate foot rot or an injury. Observe the bedding and note any wet or dirty areas that need attention. Look at the waterers and feeders to ensure they are working properly.

Keep a simple log of environmental conditions. Record the temperature inside and outside the barn, the humidity if you have a hygrometer, and any adjustments you made to ventilation. Note when you added bedding and when you cleaned the pens. This log helps you understand how the barn performs in different weather conditions and helps you plan for future improvements.

Track animal health events in a separate record. Record any cases of pneumonia, foot rot, mastitis, or other diseases. Note the pen or area where the affected animal was housed. This information helps you identify patterns. For example, if pneumonia cases always occur in the same pen, the ventilation in that area may be inadequate. If foot rot cases increase after a rainy period, your drainage may be failing.

Production records also reflect housing quality. Track lamb survival rates, weaning weights, and ewe body condition scores. A decline in these measures may indicate a housing problem. For example, if lamb survival drops during a cold spell, your lambing shed may not be providing enough protection. If ewes lose body condition in winter, they may not be able to access enough feed or may be spending too much energy staying warm.

Review your records monthly and annually. Look for trends and make adjustments to your housing system accordingly. The goal is continuous improvement. Each year, you should be making small changes that improve the comfort and health of your flock.

When to Call a Veterinarian or Extension Agent

Most housing problems can be solved with observation and adjustment. However, some situations require professional help. Knowing when to call a veterinarian or extension agent can save you time and money and can prevent serious problems.

Call your veterinarian if you see a pattern of disease that you cannot explain. For example, if multiple sheep develop pneumonia despite good ventilation, there may be an underlying issue. Your veterinarian can help you diagnose the problem and recommend changes to your housing or management. Similarly, if foot rot persists despite good hygiene, your veterinarian can help you identify the cause and develop a treatment plan.

Call your veterinarian immediately if you have an animal in distress. This includes ewes that are struggling to give birth, animals that are down and cannot rise, or animals with severe injuries. Do not wait to see if the animal improves. Early intervention improves the chances of a positive outcome.

Your local cooperative extension agent can help with design and management questions. Extension agents have training in animal housing and can provide guidance on ventilation, space requirements, and facility design. They can also connect you with local resources, such as soil testing services or equipment suppliers. Many extension offices offer workshops and publications on sheep housing and management.

The USDA Animal and Plant Health Inspection Service (APHIS) provides information on animal health regulations and disease surveillance. If you suspect a reportable disease, you are required to report it to your state veterinarian or to APHIS. Your veterinarian can help you determine whether a disease is reportable and can assist with the reporting process.

The FAO Animal Production and Health division provides international resources on livestock production, including housing recommendations for different climates. These resources are useful if you are planning a new facility or if you are considering a different production system.

Frequently Asked Questions

How much space do I need per sheep in a barn?

Adult ewes need 15 to 20 square feet of barn space each. During lambing, provide 30 to 40 square feet per ewe in the lambing area. Feeder lambs need 8 to 12 square feet each. Rams need 30 to 40 square feet each. These are minimums, and more space is better, especially in hot weather or when ewes are heavily pregnant.

Can I keep sheep outside year-round without a barn?

Yes, many producers keep sheep on pasture year-round with only a simple three-sided shelter. Sheep are hardy animals that tolerate cold well if they stay dry and are protected from wind. Provide 10 to 12 square feet of shelter space per ewe, and ensure the shelter is on well-drained ground with the opening facing away from prevailing winds.

What is the best flooring for a sheep barn?

The best flooring depends on your budget and management system. Concrete is the most durable and easiest to clean, but it is hard on sheep legs and requires generous bedding. Well-drained dirt or gravel is cheaper and provides good drainage, but it is harder to sanitize. Slatted floors keep sheep clean but are expensive. For most small and medium operations, a well-drained dirt or gravel floor with regular bedding works well.

How do I ventilate a sheep barn in winter without making it too cold?

The key is to remove moisture and ammonia while providing fresh air without creating drafts at animal level. Provide a ridge opening for stale air to escape and side openings for fresh air to enter. A general guide is 4 to 6 air changes per hour in winter. If you see condensation on the walls or smell ammonia, increase ventilation. Sheep can tolerate cold if they are dry and draft-free.

How often should I clean the sheep barn?

The cleaning schedule depends on your bedding system. In a deep-bedded system, add fresh bedding on top of old material and clean the entire barn once or twice a year. In a scrape-out system, remove all bedding and manure every few weeks. Always remove wet or dirty bedding promptly to prevent foot rot and mastitis. The lambing area should be cleaned between each ewe that uses an individual lambing pen.

What size should lambing pens be?

Individual lambing pens should be 4 feet by 5 feet or 5 feet by 6 feet. This gives the ewe enough room to lie down and stand up while keeping the lambs close. The pens should have solid sides at least 3 feet high. Some producers use group pens of 5 to 10 ewes for the early stages of labor, then move ewes to individual pens after they give birth.

How do I keep lambs warm in the lambing shed?

Newborn lambs cannot regulate their body temperature well. Keep the lambing shed at 40 to 50 degrees Fahrenheit and free of drafts. Provide deep, dry bedding for insulation. In very cold climates, heat lamps can provide supplemental warmth, but they must be placed securely and kept away from bedding to prevent fires. A creep area with a heat source can help lambs stay warm while the ewe is resting.

Should I use a hoop barn or a traditional barn for sheep?

Both designs work well. Hoop barns are cheaper and quicker to erect, and they provide good ventilation. The main drawback is that the fabric covering may need replacement every 5 to 10 years. Traditional barns are more durable and easier to insulate, but they cost more and require more careful ventilation design. Choose the design that fits your budget, climate, and management style.
