# Duck Coop Design: Ventilation, Space, and Predator Protection ## Key Takeaways - **Moisture Management is Paramount:** Ducks exude significantly more moisture than chickens due to higher water intake and wetter droppings, necessitating aggressive ventilation (1 sq ft opening per 10 sq ft floor space) to prevent condensation, ammonia buildup, and subsequent foot infections and respiratory distress. - **Ground-Level Access is Critical:** Unlike chickens, ducks are ground-dwelling and do not roost; therefore, coop entrances and ramps must be low or flush with the ground to ensure easy access and prevent exposure to predators. - **Predator Defense Requires Subterranean Security:** Effective predator protection necessitates burying 1/2-inch or 1/4-inch hardware cloth at least 12 inches deep and extending it 12 inches outward from the coop and run perimeter to deter digging predators like raccoons and foxes. - **Material Selection Dictates Efficacy:** Hardware cloth (1/2-inch or 1/4-inch mesh) is essential for all openings and enclosures, as chicken wire is insufficient to prevent predator entry, and materials like cedar shavings should be avoided due to potential respiratory irritation. - **Space Allocation Impacts Health:** Minimum space requirements of 4-6 sq ft per standard duck indoors and 10-15 sq ft per duck in the run are crucial for moisture management and preventing overcrowding-related respiratory issues and stress. --- Ducks have different housing needs than chickens, and many new duck keepers learn this only after their birds suffer from moisture problems, respiratory issues, or predation. This guide covers the complete process of designing and building a duck coop that keeps your flock healthy and secure. You will learn how to calculate space requirements, design a ventilation system that controls moisture without creating drafts, and build predator defenses that work against the specific threats in your area. The information here is for small farm owners, homesteaders, and backyard poultry keepers who want practical, buildable answers rather than general advice. ## At a Glance - **Indoor space:** Provide 4 to 6 square feet per standard duck inside the coop and 10 to 15 square feet per duck in the run. - **Ventilation is the top priority:** Ducks produce far more moisture than chickens. Place ventilation high in the coop to remove humid air while keeping birds out of drafts at floor level. - **Predator protection starts below ground:** Bury hardware cloth at least 12 inches deep and extend it outward 12 inches to stop diggers. - **Use hardware cloth, not chicken wire:** Chicken wire keeps ducks in but does not keep predators out. Use 1/2 inch or 1/4 inch hardware cloth for all openings. - **Door height matters:** Ducks do not fly up to roosts like chickens. All ramps and door thresholds must be low or flush with the ground. - **Plan for winter moisture:** A duck coop without adequate winter ventilation will develop frost on the walls and wet bedding that leads to foot problems. - **Elevate the coop floor:** A floor raised 12 to 24 inches off the ground reduces rot, discourages rodents, and gives predators less cover. ## Why Duck Housing Is Different from Chicken Housing Most poultry housing advice you will find online comes from the chicken world. Chickens roost on elevated perches, tolerate drier conditions, and spend much of their day scratching through bedding. Ducks are fundamentally different in three ways that shape every housing decision. First, ducks produce an enormous amount of moisture. A duck drinks roughly twice as much water as a chicken of the same weight, and they splash water everywhere when they drink. Their droppings are also much wetter than chicken droppings. A flock of six ducks can easily add several gallons of moisture to a coop every day. If your coop does not move that moisture out, you will fight wet bedding, ammonia, frost, and foot infections all winter. Second, ducks are ground birds. They do not roost on elevated perches at night. They prefer to sleep directly on the floor, and they need easy ground-level access to their housing. A ramp that works fine for chickens may discourage ducks from going inside at night, leaving them exposed to predators. Third, ducks are more cold-hardy but more vulnerable to dampness. A duck can tolerate very cold air as long as its feathers stay clean and dry. Wet bedding mats feathers, breaks down their natural waterproofing, and leads to hypothermia even in mild weather. The most dangerous condition for a duck is not cold air, it is cold air combined with wet feathers and wet bedding. These three differences mean you cannot simply convert a [chicken coop](/knowledge/veterinary-medicine/backyard-poultry/chicken-coop) and call it done. You need to design specifically for ducks, starting with space calculations and moving through ventilation, flooring, and predator defense. ## Space Requirements for Ducks ### Indoor Coop Space The minimum indoor space for standard-sized ducks is 4 to 6 square feet per bird. This is the floor area inside the coop where ducks sleep and shelter from weather. For a flock of six ducks, you need a coop with at least 24 to 36 square feet of floor space. A 6 by 6 foot coop provides 36 square feet, which comfortably houses six standard ducks. Bantam ducks need slightly less space, about 3 to 4 square feet per bird. Heavy breeds like Pekins, Rouens, and Muscovies may need more, closer to 6 to 8 square feet per bird, because they are larger and produce more moisture. If you plan to keep ducks confined indoors for extended periods during harsh winter weather, increase the space to 8 to 10 square feet per bird. The indoor space calculation is not just about comfort. It is about moisture management. More ducks in less space means more moisture per cubic foot of air, which overwhelms your ventilation system. Overcrowding is the most common cause of persistent respiratory problems and wet bedding in duck coops. ### Run Space The outdoor run should provide 10 to 15 square feet per duck. This gives ducks room to forage, preen, and exercise. A run that is too small becomes muddy and unsanitary very quickly because ducks compact the soil and their wet droppings turn ground into mud. For a flock of six ducks, plan a run of at least 60 to 90 square feet. A run that is 10 feet by 8 feet provides 80 square feet, which works well. If you cannot provide this much run space, you need a plan for rotating the run area or regularly adding fresh bedding material like wood chips to manage mud. ### Height and Layout Considerations Duck coops do not need to be tall. A ceiling height of 4 to 5 feet is sufficient for standard ducks. You need enough height to stand comfortably if you will be cleaning the coop regularly, but ducks do not use vertical space the way chickens do. A lower ceiling actually helps retain heat in winter, which reduces the temperature difference that drives condensation. Inside the coop, keep the layout simple. Ducks need a clear floor area for sleeping, a protected area for feed and water (or water kept outside), and a low entrance. Do not install elevated roosts or nesting boxes. Ducks lay eggs on the floor, usually in a corner or under cover. A simple floor nest area with straw or wood shavings works better than any box. ## Ventilation: The Most Critical Design Element ### Why Ducks Need Aggressive Ventilation Ducks exhale moisture with every breath, and their droppings release moisture as they decompose. In a closed coop, this moisture has nowhere to go. When warm, moist air meets a cold surface like a wall or roof, it condenses into liquid water. This condensation wets the bedding, wets the ducks, and creates the exact conditions that cause frostbite on feet, respiratory infections, and feather damage. Ammonia is the second reason ventilation matters. Duck droppings break down quickly and release ammonia gas. High ammonia levels irritate the respiratory tract, make ducks more susceptible to disease, and can cause eye irritation and reduced feed intake. You should be able to walk into your duck coop and smell only clean bedding. If you smell ammonia, your ventilation is inadequate. ### The Ventilation Principle: High In, High Out The most effective ventilation design for a duck coop uses the stack effect. Warm, moist air rises. You need vents at the top of the coop that allow this air to escape, and you need fresh air entering lower down. The height difference between the inlet and outlet creates natural air movement even when there is no wind. Place your exhaust vents at the highest point of the coop, ideally along the ridge or in the upper portion of the walls. Place intake vents lower, but still above duck height. A gap under the eaves or vents near the top of the walls on the opposite side from the exhaust works well. The critical rule is this: ventilation should move air above the ducks, not directly on them. Ducks are ground birds and they are protected by their feathers, but constant drafts at floor level stress them and make them use energy to stay warm. High ventilation removes moisture without creating floor-level drafts. ### Calculating Ventilation Area A good rule of thumb for duck coops is 1 square foot of ventilation opening per 10 square feet of floor space. This is a starting point, not a hard number. You may need more ventilation in humid climates or if you keep a large flock in a small space. For a 6 by 6 foot coop with 36 square feet of floor space, you need roughly 3.5 to 4 square feet of ventilation opening. This can be split between intake and exhaust. For example, you could have two 1 square foot exhaust vents at the ridge and two 1 square foot intake vents near the top of the walls. ### Managing Ventilation Seasonally The ventilation challenge changes with the seasons. In summer, you want maximum airflow to keep the coop from overheating. Open all vents fully and consider adding a second opening on the opposite side for cross ventilation. In winter, the instinct is to close up the coop to keep ducks warm. This is a mistake. A closed coop fills with moisture, and that moisture causes more cold stress than a draft ever would. Keep ventilation open in winter, but direct it high above the birds. You want the coop to be dry and cool, not warm and wet. A simple winter ventilation strategy is to keep the ridge vent fully open and partially close the lower intake vents. This reduces the total air exchange while still removing moisture. Monitor the inside of the coop for condensation on the walls or ceiling. If you see frost or water droplets, you need more ventilation, not less. ### Testing Your Ventilation You can test your coop ventilation with a simple method. On a cold morning, enter the coop before the ducks go out. If you feel a noticeable difference in air quality compared to outside, and if you see condensation on any surface, your ventilation is inadequate. The air inside should feel fresh and dry. There should be no fog, no dripping water, and no frost on the walls. Another test is to hold a lit match or lighter near the exhaust vent. If the flame flickers or moves toward the vent, air is flowing out. If the flame is still, you have a ventilation dead zone and need to adjust your vent placement. ## Flooring and Bedding ### Floor Construction The coop floor must be solid, dry, and easy to clean. A wooden floor raised 12 to 24 inches off the ground is the most common choice for small duck coops. The elevation keeps the floor dry, reduces rot, and makes it harder for predators to dig underneath. For the floor itself, use exterior-grade plywood at least 3/4 inch thick, or use tongue-and-groove boards. Cover the floor with a waterproof membrane or heavy-duty linoleum to protect the wood from moisture. Ducks are hard on floors. Their wet feet, splashing water, and wet droppings will rot unprotected wood within a year or two. An alternative is a concrete floor, which is more durable but harder to clean and colder in winter. If you use concrete, slope it slightly toward a drain or the door so you can wash it out with a hose. Add deep bedding to insulate the ducks from the cold concrete. ### Bedding Materials The best bedding for duck coops is one that absorbs moisture, dries quickly, and composts well. Pine shavings are the most common choice. They absorb well, smell pleasant, and are inexpensive. Avoid cedar shavings because the oils can irritate duck respiratory systems. Straw is another option, especially for nest areas. Straw holds its shape better than shavings and provides good insulation, but it absorbs less moisture. Many duck keepers use a combination: pine shavings over the main floor and straw in the nesting corners. Do not use sand or [cat litter](/knowledge/veterinary-medicine/clinical-methods/cat-litter) in a duck coop. Sand does not absorb moisture and becomes cold and wet. [Cat litter](/knowledge/veterinary-medicine/clinical-methods/cat-litter) contains chemicals and clumping agents that are dangerous if ingested. ### Bedding Management Duck bedding needs to be changed more often than chicken bedding because of the moisture load. A good routine is to remove wet spots daily and do a full bedding change weekly. In winter, when ducks spend more time indoors, you may need to change bedding twice weekly. The deep litter method, where bedding is allowed to accumulate and compost in place, does not work well with ducks. The moisture load is too high and the bedding becomes anaerobic and foul. Stick with regular removal and replacement. ### Managing the Water Area The single biggest source of moisture in a duck coop is the waterer. If you keep water inside the coop, you are adding gallons of moisture to the air every day. The best design keeps water outside the coop, in the run or in a separate covered area. If you must keep water inside for winter, use a heated waterer and place it over a drainage area or in a large shallow pan that catches splashes. Check the water area frequently and remove wet bedding around it promptly. Some duck keepers build a small water station just outside the coop door with a partial roof, so ducks can drink without standing in rain or snow. ## Predator Protection ### Understanding the Threat Predators are the leading cause of duck losses on small farms. Ducks are especially vulnerable because they are ground birds that cannot fly to safety, and they are often kept in coops that were designed with chickens in mind. A predator that can dig, climb, or chew through a [chicken coop](/knowledge/veterinary-medicine/backyard-poultry/chicken-coop) will have no trouble with ducks. Common predators vary by region but include raccoons, opossums, skunks, foxes, coyotes, weasels, minks, rats, owls, hawks, and domestic dogs. Each predator has different capabilities, and your defense must address all of them. ### Hardware Cloth: The Only Wire That Works The most important predator protection decision is the type of wire you use. Chicken wire is not predator-proof. A raccoon can tear through it in minutes, and a determined dog can push through it. Weasels and minks can squeeze through the 1 inch openings. Use hardware cloth with 1/2 inch or 1/4 inch mesh for all coop windows, vents, and run enclosures. Hardware cloth is welded wire that is much stronger than chicken wire. The 1/4 inch mesh also keeps out mice and rats, which are attracted to duck feed and can chew through wood and plastic. Do not use plastic netting or poultry netting for predator protection. These materials are for keeping birds in, not for keeping predators out. ### Securing the Floor and Perimeter Most predators dig. A raccoon or fox will dig under a fence or coop wall in minutes. To stop diggers, you have three options. The first option is to bury hardware cloth. Dig a trench at least 12 inches deep along the outside of the coop walls and run enclosure. Attach hardware cloth to the bottom of the walls and extend it outward into the trench, away from the coop, for at least 12 inches. The outward extension is critical because predators dig down along the wall. If the wire extends outward, they hit it as they dig and give up. The second option is to use a solid floor. A raised coop with a solid wood floor eliminates the digging problem entirely. The run should still have buried wire because predators will dig into the run. The third option is to pour a concrete skirt around the coop and run. This is the most expensive option but also the most permanent. A 4 inch thick concrete apron extending 12 to 18 inches outward from the walls stops all diggers. ### Securing Doors and Windows Doors are the most common entry point for predators. A predator that cannot dig under the wall will try the door. Use solid wood doors that close tightly with no gaps. Install a latch that requires two steps to open, such as a hook-and-eye latch plus a sliding bolt. Raccoons have dexterous [paws](/knowledge/veterinary-medicine/clinical-methods/paws) and can open simple latches. A carabiner clip on the latch adds another layer that most raccoons cannot figure out. Windows and vents must be covered with hardware cloth, not just on the inside but ideally on the outside as well. A predator can rip hardware cloth off the inside of a window frame. If you attach it to the exterior, the frame itself provides extra strength. ### Nighttime Security Ducks should be locked inside the coop every night, without exception. Most predation happens between dusk and dawn. A duck left in an open run at night is an invitation to every predator in the area. Train your ducks to go into the coop at dusk. This is easier than it sounds. Ducks naturally seek shelter as light fades. Establish a routine of closing the coop door at the same time each evening. If you have ducks that resist going in, use a small amount of feed scattered inside the coop to lure them. Check the coop perimeter regularly for signs of digging, scratching, or chewing. Fresh dig marks along the walls are a warning that a predator is testing your defenses. Address these immediately before they become a breach. ### Predator-Specific Considerations Raccoons are the most common duck predator in North America. They are strong, smart, and persistent. They will open latches, tear through chicken wire, and dig under walls. Your coop must have hardware cloth, secure latches, and buried wire to stop them. Weasels and minks are smaller but deadly. They can squeeze through gaps as small as 1 inch and will kill an entire flock in one night. Seal all gaps larger than 1/2 inch and use 1/4 inch hardware cloth on all openings. Owls and hawks are a threat during the day, especially to ducks in an open run. A covered run provides the best protection. If a full cover is not possible, provide dense shrubbery or structures that give ducks a place to hide from aerial predators. Dogs, both domestic and feral, are a serious threat. A dog can break through most fencing. If dogs are a problem in your area, use a solid fence at least 5 feet tall around the run, and consider an electric wire at the top. ## Building Your Duck Coop: Step by Step ### Step 1: Choose Your Location Place the coop in a location that is well-drained and slightly elevated. Ducks are messy and the area around the coop will become muddy. A slight slope helps water drain away. Avoid low spots that collect standing water. Orient the coop so the entrance faces south or east. This gives ducks morning sun and protects the entrance from prevailing winter winds. If you live in a hot climate, orient the longest wall to face north and south to reduce summer heat gain. ### Step 2: Determine Your Flock Size and Space Needs Calculate your indoor and run space before you build. Use 4 to 6 square feet per standard duck indoors and 10 to 15 square feet per duck in the run. Add 25 percent to your space calculation as a buffer for future flock growth or temporary confinement during bad weather. ### Step 3: Build the Floor and Frame Build a floor frame from pressure-treated lumber. Attach exterior-grade plywood to the top. Cover the floor with a waterproof membrane or linoleum. Raise the floor 12 to 24 inches off the ground on concrete blocks, pavers, or pressure-treated skids. This elevation protects the floor from moisture and makes it harder for predators to dig under. ### Step 4: Install Walls and Ventilation Frame the walls with standard lumber. Install solid wood sheathing on the lower portion of the walls to block drafts at duck level. Use hardware cloth covered openings in the upper portion for ventilation. Plan your ventilation openings before you build so you can frame them properly. ### Step 5: Build the Roof with Ridge Ventilation A gable roof with a ridge vent is the best design for duck coop ventilation. The ridge vent runs the full length of the roof peak and allows warm, moist air to escape continuously. Build the ridge vent by leaving a 2 to 3 inch gap at the peak and covering it with a small roof cap or commercially available ridge vent material. Cover the opening with hardware cloth to keep out predators. ### Step 6: Install the Door The duck door should be at floor level, large enough for your largest duck to pass through comfortably. A door that is 12 inches wide and 14 inches tall works for standard ducks. Install a solid drop-down door or a sliding door that you can close securely from the outside. If the coop floor is elevated, build a ramp from the ground to the door. The ramp should have a gentle slope, no more than 30 degrees, with cleats or traction strips so ducks can climb it even when wet. Some duck keepers prefer a rampless design where the door opens directly onto a low porch or landing. ### Step 7: Secure the Run Build the run with a frame of pressure-treated lumber. Attach 1/2 inch hardware cloth to the entire frame, including the top. Bury the hardware cloth at least 12 inches deep and extend it outward 12 inches along the entire perimeter. Use staples every 4 to 6 inches to attach the wire, and overlap seams by at least 2 inches. ### Step 8: Add Interior Features Inside the coop, add a low partition or corner area filled with straw for nesting. Do not add elevated roosts. Provide a shallow pan or tray for feed that ducks cannot tip over. If water must be inside, place it over a drainage tray and check it frequently. ### Step 9: Test Before Introducing Ducks Before you move ducks in, test the coop for a few days. Check that the door closes securely from the outside. Verify that all ventilation openings are covered with hardware cloth. Look for any gaps larger than 1/2 inch anywhere in the structure. Pour water on the roof and check for leaks. Open and close the door several times to confirm the latch is secure. ## Common Mistakes in Duck Coop Design ### Mistake 1: Using a Chicken Coop Design The most common mistake is converting a chicken coop without modification. Chicken coops have elevated roosts, small pop holes, and inadequate ventilation for ducks. Ducks will sit on the floor, get wet bedding, and develop respiratory problems. If you must convert a chicken coop, remove the roosts, enlarge the pop hole to floor level, and add significantly more ventilation. ### Mistake 2: Inadequate Ventilation Many duck keepers under-ventilate because they worry about cold drafts. The result is a damp, ammonia-filled coop that causes more health problems than any draft. Ducks tolerate cold air far better than they tolerate wet bedding. When in doubt, err on the side of more ventilation. ### Mistake 3: Using Chicken Wire Chicken wire is not predator-proof. It keeps ducks in but does not keep predators out. A single raccoon can destroy a flock through chicken wire. Use 1/2 inch hardware cloth for all predator protection. ### Mistake 4: Ignoring the Digging Problem A coop with secure walls but an unprotected floor perimeter will be breached. Foxes, raccoons, and dogs dig. Bury hardware cloth at least 12 inches deep and extend it outward. This is not optional. ### Mistake 5: Keeping Water Inside the Coop Water inside the coop adds massive amounts of moisture to the air. This overwhelms ventilation and creates wet bedding. If you keep water inside for winter convenience, you must be prepared for much more frequent bedding changes and heavier ventilation. ### Mistake 6: Building the Coop Too Small Underestimating space needs leads to overcrowding, which amplifies every other problem. Moisture increases, ammonia increases, and disease spreads faster. Build for your current flock plus room to grow. ### Mistake 7: Placing the Coop in a Low, Wet Area A coop in a poorly drained location sits in mud all winter. The moisture wicks up into the floor and bedding. Choose a well-drained, slightly elevated site. ## Decision Thresholds: When to Upgrade or Redesign ### You Need More Ventilation If - You see condensation on the walls or ceiling on any morning - The air inside smells ammonia-like when you enter - Bedding stays wet even after a fresh change - Ducks show signs of respiratory distress, such as open-mouth breathing or nasal discharge - Frost forms on the inside of the walls or roof in winter ### You Need More Space If - Ducks cannot all lie down comfortably at the same time - The bedding becomes saturated within a day of changing - Ducks show signs of stress, such as feather pecking or fighting - The run is bare mud with no vegetation ### You Need Better Predator Protection If - You find dig marks along the walls or run perimeter - You see predator tracks or droppings near the coop - A predator has attempted to enter, even if it did not succeed - You are using chicken wire anywhere in the structure ### You Need a Full Redesign If - The coop has chronic moisture problems despite increased ventilation - The floor has rotted or is structurally unsound - The coop is too small to safely house your flock and cannot be expanded - The location is so poorly drained that the coop sits in standing water ## Monitoring and Recordkeeping ### Daily Checks Walk the coop perimeter every morning and evening. Look for dig marks, chew marks, or any signs of predator activity. Check that all latches are secure and all hardware cloth is intact. Observe your ducks as they exit the coop in the morning. Healthy ducks are active, alert, and eager to get out. Lethargy, hesitance to exit, or reluctance to move may indicate a problem. Check the bedding condition daily. If it is wet in the morning, your ventilation or water management needs adjustment. Remove any wet spots immediately. ### Weekly Checks Do a full inspection of the coop structure weekly. Check for loose staples, gaps in the hardware cloth, and signs of rodent activity. Look for droppings from rats or mice, which indicate a food source access point that needs sealing. Check the condition of the ramp and door. A warped door may not close fully, creating a predator gap. A slippery ramp can cause leg injuries. ### Recordkeeping Keep a simple coop log with the following information: - Date of bedding changes - Any signs of illness or injury - Predator sightings or attempts - Repairs made - Egg production changes - Weather events that affected the coop This log helps you spot patterns. If respiratory problems appear every January, you know your winter ventilation needs adjustment. If predator attempts cluster in late summer, you know to increase vigilance during that season. ## When to Call a Veterinarian or Extension Agent Most duck coop design problems show up as health problems in the flock. You should contact a veterinarian experienced with poultry if you see any of the following: - Persistent respiratory signs: coughing, sneezing, nasal discharge, or open-mouth breathing - Sudden death of one or more ducks with no obvious cause - Lameness or reluctance to walk - Swollen or discolored feet - Reduced feed or water intake lasting more than a day - Significant drop in egg production - Feather loss beyond normal molting - Any signs of injury from a predator attack A veterinarian can help you determine whether a health problem is caused by housing conditions or by an infectious disease. Do not wait until multiple birds are sick. Ducks hide illness well, and by the time you notice a problem, it may be advanced. Your local cooperative extension agent can help with coop design questions, predator identification, and regional disease concerns. Extension agents know the specific predators and climate challenges in your area and can recommend proven solutions. Contact them before you build, not just when problems arise. ## Frequently Asked Questions ### How much space do ducks need in a coop? Standard ducks need 4 to 6 square feet of indoor floor space per bird and 10 to 15 square feet per bird in the outdoor run. Heavy breeds like Pekins need more, closer to 6 to 8 square feet indoors. Bantams need less, about 3 to 4 square feet. These numbers are minimums, not targets. More space always makes moisture management easier. ### Do ducks need a heated coop in winter? Ducks do not need supplemental heat in most climates. Their down feathers provide excellent insulation, and they are far more cold-hardy than chickens. The real danger in winter is moisture, not cold. A well-ventilated, dry coop is the best winter protection. Adding a heat lamp can actually cause problems by increasing the temperature difference that drives condensation and by creating a fire hazard. ### Can I keep ducks in a chicken coop? You can convert a chicken coop for ducks, but you must make significant modifications. Remove all elevated roosts because ducks sleep on the floor. Enlarge the pop hole so it is at floor level and large enough for ducks to pass through easily. Ducks do not fly up to small elevated entrances. Most importantly, add substantially more ventilation because ducks produce far more moisture than chickens. ### What is the best bedding for a duck coop? Pine shavings are the best all-around bedding for duck coops. They absorb moisture well, dry quickly, and are inexpensive. Use straw in nesting corners for extra insulation and structure. Avoid cedar shavings because their oils can irritate duck respiratory systems. Avoid sand and cat litter because they do not absorb moisture well and can be dangerous if ingested. ### How do I keep predators from digging into the duck coop? Bury hardware cloth at least 12 inches deep along the outside of all walls and the run perimeter. Extend the wire outward at the bottom of the trench for at least 12 inches. This outward extension is critical because predators dig down along the wall. The wire stops them before they can tunnel under. A raised coop with a solid floor also eliminates the digging problem for the coop itself. ### How much ventilation does a duck coop need? A good starting point is 1 square foot of ventilation opening per 10 square feet of floor space. For a 6 by 6 foot coop with 36 square feet of floor, you need about 3.5 to 4 square feet of ventilation. Place exhaust vents at the highest point of the coop and intake vents lower, but above duck height. The goal is to move moist air out without creating drafts at floor level. ### Do ducks need a ramp to get into their coop? Ducks are ground birds and do not climb well. If your coop floor is elevated, provide a ramp with a gentle slope of no more than 30 degrees. Add cleats or traction strips so ducks can climb even when the ramp is wet. Many duck keepers prefer a coop with the door at ground level or on a low landing to eliminate the ramp entirely. ### How often should I clean the duck coop? Remove wet spots and droppings daily. Do a full bedding change weekly, or more often in winter when ducks spend more time indoors. The water area needs the most frequent attention. Check it daily and remove any wet bedding around it immediately. A clean duck coop should not smell like ammonia when you enter. ## Related Farming Guides - [Duck Coop Design and Management: Creating a Safe and Functional Habitat](/knowledge/veterinary-medicine/backyard-poultry/duck-coop-design-and-management-creating-a-safe-and-functional-habitat) This section will be populated with links to related farming guides on duck care, poultry health, and small farm infrastructure.
