# Mobile Chicken Coops: Design and Pasture Rotation Benefits ## Key Takeaways - Mobile chicken coops, also known as chicken tractors, facilitate pasture rotation by allowing flocks to be moved every 1-7 days, providing fresh forage and insects while evenly distributing nutrient-rich manure across the land. This practice breaks parasite cycles by allowing grazed areas to rest for 3-6 weeks, promoting soil health and reducing re-infection in birds. - Different mobile coop designs cater to varying flock sizes and terrains: A-frame tractors (2-6 birds) are lightweight for level ground, hoop houses (10-30 birds) offer more space, trailer-mounted coops (30-100+ birds) are for larger operations, and skid-mounted coops (10-25 birds) provide stability on uneven terrain. - Optimal stocking density ranges from 10 to 50 square feet per bird per day, contingent on pasture quality, season, and coop design (floorless vs. floored), with movement triggered by vegetation grazed to 2-3 inches or visible manure buildup. - Critical management tasks include daily water and feed checks, weekly cleaning of floored coops, monthly equipment inspection, and proactive parasite monitoring via fecal samples, with veterinary consultation advised for signs of respiratory distress, sudden death, severe diarrhea, or a significant drop in egg production (>20% in a few days). - Seasonal management is crucial: spring offers rapid grass growth for frequent moves (3-5 days), summer requires attention to shade and ventilation with more frequent moves due to heat and fly issues, fall necessitates longer rest periods (5-7 days) as growth slows, and winter presents challenges with frozen ground, often requiring sheltered placement or less frequent movement. --- A mobile [chicken coop](/knowledge/veterinary-medicine/backyard-poultry/chicken-coop), often called a [chicken tractor](/knowledge/animal-farming/poultry/chicken-tractor-design-and-pasture-management-for-broilers) or movable [chicken coop](/knowledge/veterinary-medicine/backyard-poultry/chicken-coop), is a portable poultry shelter that lets you move your flock across your land on a regular schedule. This guide compares the main design options for mobile coops, explains how pasture rotation with chickens improves soil and bird health, and gives you step-by-step instructions for building, positioning, and managing a portable poultry shelter. This article is for small to mid-scale farmers, homesteaders, and backyard keepers who want to integrate chickens into a grazing system or who are deciding between a fixed coop and a movable one. ## At a Glance - **What a mobile coop is:** A floorless or floored shelter on wheels, skids, or a trailer that you move every 1 to 7 days. - **Main benefit:** Birds get fresh forage, insects, and sunlight while depositing manure evenly across the pasture instead of concentrating it in one spot. - **Best designs for most people:** The A-frame chicken tractor for 2 to 6 birds on level ground, the hoop house for 10 to 30 birds, and the trailer-mounted coop for 30 to 100 birds on larger acreage. - **Rotation basics:** Move the coop when the vegetation is grazed down to about 2 to 3 inches, manure is visible but not caked, or after 2 to 4 days in warm weather. - **Stocking density range:** 10 to 50 square feet per bird per day depending on pasture quality, season, and whether you use a floorless or floored design. - **Key management tasks:** Daily water and feed checks, weekly coop cleaning if floored, monthly inspection of wheels and frame, and parasite monitoring through fecal samples. - **When to get help:** Call a veterinarian if birds show signs of respiratory distress, sudden death, severe diarrhea, or a drop in egg production of more than 20 percent in a few days. ## Why Use a Mobile Chicken Coop The fixed chicken house has been the standard for generations, but it comes with hidden costs. When birds stay in one place, manure builds up in the same footprint week after week. Nitrogen and phosphorus concentrate in the soil under and around the coop. Fly populations explode in warm weather. Internal parasite eggs accumulate in the ground, and your birds keep re-infecting themselves by scratching in the same contaminated dirt. A mobile chicken coop solves these problems by turning the flock into a moving fertility tool. Instead of hauling manure out of a fixed house, you let the birds spread it themselves. The pasture gets a light, even dressing of nitrogen-rich manure. The birds get fresh forage, insects, and ground to scratch. The soil gets a rest period after the birds move on, which breaks the parasite cycle and lets grass recover. The comparison is not just about convenience. It is about what kind of system you want to run. A fixed coop works well if you have a small backyard flock and you are willing to clean it regularly. A mobile coop works better if you want to improve pasture, reduce feed costs, and manage parasites without daily cleaning. ## Understanding the Different Mobile Coop Designs Before you build or buy, you need to match the design to your flock size, your land, and your physical ability to move the coop. There is no single best design. The right choice depends on how many birds you keep, how often you can move the coop, and what kind of ground you have. ### The A-Frame Chicken Tractor The A-frame is the classic chicken tractor design. It looks like an upside-down V with a sloped roof on both sides. The frame is usually made of 2x4 lumber, and the sides are covered with hardware cloth for ventilation and predator protection. A small access door on one end lets you reach in for eggs and feed, and a larger door on the other end lets you move the birds in and out. **Best for:** 2 to 6 birds, level ground, and keepers who want a lightweight unit they can drag by hand. **Pros:** - Lightweight, usually 50 to 100 pounds empty - Low cost to build, often under $200 in materials - Easy to move by one person on level ground - Small footprint fits in backyard gardens **Cons:** - Too small for more than a few birds - Low interior height makes it hard to stand inside - Needs frequent moves because the small footprint concentrates manure quickly - Not suitable for rough or sloping ground ### The Hoop House or PVC Tunnel Coop The hoop house design uses bent PVC pipes or metal conduit to form an arched frame. You cover the frame with hardware cloth and a tarp or shade cloth over the top. The floor is open, so birds have direct access to grass. This design is longer and wider than the A-frame, giving birds more room to move. **Best for:** 10 to 30 birds, moderate pasture, and keepers who want a larger footprint without a heavy frame. **Pros:** - More interior space per bird than an A-frame - Cheaper per square foot than wood-frame designs - Can be moved by two people or dragged with a small vehicle - Good ventilation because of the open ends **Cons:** - PVC can become brittle in cold weather - Tarp covers need replacement every 1 to 3 years - Not as predator-proof as a solid wood frame unless you bury the edges - Can be awkward to move in wind ### The Trailer-Mounted Coop A trailer-mounted coop is a full-size chicken house built on a flatbed trailer or a repurposed utility trailer. It has a solid floor, walls, a roof, nest boxes, and roosting bars. You move it with a truck, ATV, or tractor. This is the design used by many pastured egg operations that keep 50 to 500 birds. **Best for:** 30 to 100 birds, larger acreage, and keepers who have a vehicle to move the unit. **Pros:** - Large enough for a commercial-scale flock - Solid construction protects against predators and weather - Can include permanent nest boxes, feeders, and waterers - Moving takes minutes with a vehicle instead of hours by hand **Cons:** - Expensive to build or buy, often $1,500 to $5,000 or more - Requires a vehicle and a trailer hitch rated for the weight - Solid floor means you must clean it out regularly - Not suitable for steep or soft ground where a trailer might get stuck ### The Skid-Mounted Coop A skid-mounted coop is a small shed built on two or four skids, like the runners on a sled. You drag it with a tractor, ATV, or come-along winch. This design is common for 10 to 25 birds and works well on pasture that is not perfectly level. **Best for:** 10 to 25 birds, pasture with gentle slopes, and keepers who have a small tractor or ATV. **Pros:** - More stable than wheels on uneven ground - Can be built with standard lumber and roofing - Cheaper than a trailer-mounted unit - Skids spread the weight so the coop does not sink into soft ground **Cons:** - Dragging can tear up pasture if the ground is wet - Needs a vehicle or winch to move - Harder to reposition precisely than a wheeled unit - Skids wear out and need replacement ## Chicken Tractor Plans and Building Basics You can buy a mobile coop, but building your own is often cheaper and lets you customize the design to your exact needs. The plans below give you the key measurements and construction steps for a basic A-frame and a simple hoop house. Adjust the dimensions based on your flock size. ### Materials for a Basic A-Frame Chicken Tractor For a unit that holds 4 to 6 standard-size hens, use these materials: - 4 pieces of 2x4 lumber, 8 feet long, for the frame rails - 4 pieces of 2x4 lumber, 6 feet long, for the cross braces - 2 pieces of 3/4-inch plywood, 4x8 feet, for the end panels - 1 roll of 1/2-inch hardware cloth, 3 feet wide - 1 box of 1-inch galvanized staples or screws - 4 heavy-duty gate hinges - 2 barrel bolts or latches - Exterior-grade paint or wood sealer - 4 small wheels (optional, for one end) ### Building Steps for an A-Frame 1. **Cut the frame rails.** Cut two 2x4s to 8 feet for the bottom rails. Cut two more 2x4s to 8 feet for the top ridge. The top rails will meet at the peak. 2. **Assemble the end triangles.** Cut two pieces of plywood into triangles. Each triangle should be 8 feet wide at the base and about 4 feet tall at the peak. These form the solid ends of the coop. 3. **Attach the bottom rails.** Screw the two bottom rails to the base of the plywood triangles, one on each side. 4. **Attach the top ridge.** Screw the two top rails to the peak of the plywood triangles. The top rails meet at the center ridge line. 5. **Add cross braces.** Cut the remaining 2x4s to fit between the bottom and top rails on each side. Space them every 2 feet. These give the frame rigidity and give you something to attach the wire to. 6. **Cover with hardware cloth.** Staple the hardware cloth to the outside of the frame on both sides. Overlap the edges by at least 2 inches and use plenty of staples. The wire keeps predators out and birds in. 7. **Install doors.** Cut a door opening in one plywood end, about 18 inches square. Attach it with hinges and a latch. This is your access door for eggs, feed, and water. Cut a larger opening, about 2 feet square, in the other end for moving birds in and out. 8. **Add wheels (optional).** Attach two small wheels to one end of the bottom rails. This lets you lift the other end and roll the coop like a wheelbarrow. 9. **Paint or seal the wood.** Use exterior-grade paint or sealer to protect the frame from weather. This extends the life of your coop by years. ### Materials for a Hoop House Coop For a unit that holds 15 to 25 birds, use these materials: - 6 pieces of 10-foot PVC pipe, 1-inch diameter, for the hoops - 12 pieces of 2-foot rebar, for anchoring the hoops - 1 piece of 1-inch PVC pipe, 20 feet long, for the ridge - 1 roll of 1/2-inch hardware cloth, 4 feet wide - 1 tarp or shade cloth, 10x20 feet - 20 zip ties or pipe straps - 4 stakes or ground anchors ### Building Steps for a Hoop House 1. **Drive the rebar anchors.** Space the rebar stakes in two parallel rows, 8 feet apart. Each row has 6 stakes, spaced 4 feet apart. Drive each stake about 12 inches into the ground. 2. **Bend the PVC hoops.** Slide one end of a PVC pipe over a rebar stake. Bend the pipe over and slide the other end over the matching stake on the opposite side. This forms an arch. 3. **Install the ridge pipe.** Run the 20-foot PVC pipe along the top of the arches. Secure it to each arch with zip ties. 4. **Attach the hardware cloth.** Drape the hardware cloth over the frame. Secure it to the hoops with zip ties. Leave the ends open for now. 5. **Add the tarp.** Drape the tarp over the top half of the frame. Secure it with zip ties or bungee cords. The tarp keeps rain off the birds while the open lower sides provide ventilation. 6. **Close the ends.** Cut a piece of hardware cloth to fit each end. Attach with zip ties. Leave a 2-foot opening in one end for a door. 7. **Anchor the structure.** Use ground anchors or stakes at each corner to keep the hoop house from blowing away in high winds. ## Pasture Rotation with Chickens Moving the coop is only half the system. The other half is managing the rotation schedule so your pasture stays healthy and your birds stay productive. A poor rotation schedule can damage grass, concentrate parasites, and stress your flock. ### How Pasture Rotation Works The basic idea is simple. Birds spend a few days on one patch of ground, then you move them to a fresh patch. The used patch gets a rest period of 3 to 6 weeks before the birds return. During that rest, the grass regrows, the manure breaks down, and parasite eggs die off. The length of time birds stay in one spot depends on three factors: the number of birds, the size of the coop footprint, and the quality of the pasture. A good starting point is to move the coop every 2 to 4 days in the growing season and every 5 to 7 days in the cooler months when grass grows slowly. ### Calculating Your Rotation Schedule To figure out how often to move your coop, use this simple calculation: 1. **Measure the coop footprint.** Multiply the length by the width to get the square footage. For example, a 4x8 foot A-frame covers 32 square feet. 2. **Determine your stocking density.** For a floorless coop on good pasture, aim for 10 to 20 square feet per bird per day. For a floored coop, you can go higher, 5 to 10 square feet per bird, because the birds are not directly grazing. 3. **Calculate the days per spot.** Divide the coop footprint by the number of birds, then divide by the daily square footage per bird. For example, with 6 birds in a 32 square foot coop, each bird has about 5.3 square feet. At a target of 15 square feet per bird per day, the birds can stay about 1/3 of a day, so you would move them every 8 hours. That is too frequent. You need a bigger coop or fewer birds. 4. **Adjust for pasture quality.** On lush spring pasture, birds can stay longer because there is more forage. On thin summer pasture, move them more often. A practical rule of thumb is this: if the grass is grazed down to less than 2 inches, move the coop. If you see bare soil and heavy manure buildup, move the coop now. If the birds are scratching so hard they are creating dust bowls, they are telling you the spot is spent. ### Setting Up a Rotation Grid The easiest way to manage rotation is to divide your pasture into paddocks or blocks. You do not need permanent fencing for this. Just mark the blocks with flags or stakes, and move the coop from one block to the next in a set order. For a small operation, a simple 6-block rotation works well. Number the blocks 1 through 6. Move the coop from block 1 to block 2 to block 3, and so on. After the coop leaves block 6, it returns to block 1, which has now rested for the full rotation cycle. For a larger operation with a trailer-mounted coop, you can use the same system on a bigger scale. Some farmers use electric netting to create temporary paddocks around the coop. This lets the birds range farther from the coop during the day while still being protected from predators. ### The Role of the Floorless Design A floorless coop is the heart of a pasture rotation system. With no floor, the birds have direct access to the grass. They scratch, peck, and graze all day. Their manure drops directly onto the pasture, where it breaks down and feeds the soil. The downside is that floorless coops are harder to keep clean. You cannot scrape out bedding because there is no floor. Instead, you rely on the rotation to move the birds off the manure before it builds up. This is why the rotation schedule matters so much. If you prefer a floored coop, you can still rotate pasture, but you lose the direct grazing benefit. The birds get fresh ground to scratch and the manure is collected for you to spread elsewhere. This is a good option if you want to compost the manure or if your pasture is too fragile for direct grazing. ## Choosing Between a Mobile Coop and a Fixed Coop The decision between a mobile and fixed coop is not about which is better in general. It is about which fits your situation. Use the comparison below to make your choice. ### When a Mobile Coop Makes Sense - You have at least 1/4 acre of open ground to rotate through - You want to improve pasture fertility without spreading manure by hand - You are willing to move the coop on a regular schedule - You have a way to move the coop, whether by hand, ATV, or truck - Your ground is fairly level and free of large rocks, stumps, or deep mud - You want to reduce internal parasite pressure by breaking the worm cycle ### When a Fixed Coop Makes Sense - You have a very small yard with no room to rotate - You cannot physically move a coop or do not have a vehicle for it - Your ground is too steep, rocky, or wet for a movable structure - You prefer the convenience of permanent electricity, water, and lighting - You have a deep-litter system you want to maintain - You are keeping only a few pet birds and do not need pasture improvement ### The Cost Comparison A mobile coop costs more per square foot than a fixed coop because of the wheels, skids, and lighter construction materials. But the operating costs can be lower because you do not need to buy as much bedding or spend as much time cleaning. A basic A-frame chicken tractor costs $150 to $300 in materials if you build it yourself. A hoop house costs $200 to $500. A trailer-mounted coop costs $1,500 to $5,000 or more depending on size and materials. A fixed coop of similar capacity costs $500 to $2,000 for materials, but you will need to add permanent fencing, a concrete or gravel pad, and more bedding. Over 5 years, the total cost of ownership is often similar. The mobile coop saves on bedding and cleaning labor but costs more upfront and requires more daily management. ## Step-by-Step Guide to Starting with a Mobile Coop If you are new to mobile coops, follow this sequence to get started without making costly mistakes. ### Step 1: Assess Your Land Walk your property and look for a spot that is relatively level, well-drained, and free of hazards. Avoid low spots where water pools after rain. Avoid areas with heavy brush or poison ivy. Make sure the spot gets at least 6 hours of sunlight a day, because grass needs light to regrow after the birds move on. ### Step 2: Choose Your Coop Design Match the design to your flock size and your ability to move the coop. Start with a smaller coop than you think you need. A 4x8 foot A-frame for 4 to 6 birds is a good entry point. You can always build a bigger one later once you learn how the system works on your land. ### Step 3: Build or Buy If you build, follow the plans above or find plans from a reputable extension service. If you buy, look for a coop with solid construction, hardware cloth rather than chicken wire, and wheels or skids that match your ground conditions. ### Step 4: Start with a Small Flock Do not put 20 birds in a coop designed for 6. Start with the number the coop is designed for, or fewer. Overcrowding leads to dirty eggs, aggressive pecking, and rapid pasture damage. ### Step 5: Establish the Rotation Schedule Mark out 6 to 8 spots on your pasture. Move the coop every 2 to 4 days in warm weather and every 5 to 7 days in cool weather. Keep a simple log of when you move the coop and what the pasture looks like. ### Step 6: Monitor and Adjust Check the pasture before you move the coop. Is the grass grazed down? Is there a thick layer of manure? Are the birds scratching constantly? Use these signs to adjust your schedule. In the spring when grass grows fast, you can move less often. In late summer when grass slows, move more often. ## Common Mistakes with Mobile Coops Even experienced farmers make these mistakes. Learn from them so you do not repeat them. ### Mistake 1: Moving the Coop Too Often Moving the coop every day sounds like good management, but it can stress the birds. Chickens are creatures of habit. Constant moving means they have to re-establish their pecking order in a new space every day. This can reduce egg production and increase stress. Move the coop on a schedule that matches pasture conditions, not on a fixed daily routine. A 2 to 4 day stay is usually better than a 1 day stay. ### Mistake 2: Moving the Coop Too Rarely The opposite problem is leaving the coop in one spot for weeks. This defeats the purpose of a mobile coop. The pasture gets destroyed, manure builds up, and parasites take hold. If you cannot commit to moving the coop at least every 7 days, go back to a fixed coop with a proper cleaning routine. ### Mistake 3: Using Chicken Wire Instead of Hardware Cloth Chicken wire keeps chickens in, but it does not keep predators out. Raccoons, foxes, and dogs can tear through chicken wire in minutes. Use 1/2 inch or 1/4 inch hardware cloth for the sides and ends of your coop. It costs more but it saves your flock. ### Mistake 4: Ignoring Predator Risk at Night Mobile coops are more vulnerable to predators than fixed coops because they sit directly on the ground. Secure the coop at night by closing all doors and checking that the hardware cloth has no gaps. Bury the bottom edge of the wire 6 inches into the ground if you are in an area with digging predators. ### Mistake 5: Overlooking Ventilation A small coop heats up fast in summer. Without proper ventilation, birds can die from heat stress. Make sure your coop has open areas covered with hardware cloth on at least two sides. The A-frame design naturally provides good airflow because the sides are mostly open. ### Mistake 6: Not Protecting the Coop from Wind A lightweight mobile coop can blow over in a strong storm. Anchor the coop with stakes, sandbags, or concrete blocks. If you know a storm is coming, move the coop to a sheltered spot or tie it down. ### Mistake 7: Forgetting About Water Water is the most common oversight in mobile coop systems. You need to carry water to the coop every day, or you need a way to run a hose to it. Some farmers use large 5-gallon waterers that last several days. Others run a permanent water line to the pasture and connect a hose to the coop. Plan your water system before you build. ### Mistake 8: Overstocking the Pasture More birds per square foot means more manure and faster pasture damage. Stick to the stocking density guidelines. If your pasture is thin or your soil is poor, reduce the number of birds. ## Monitoring and Recordkeeping for Mobile Coops Good recordkeeping helps you spot problems early and improve your rotation over time. You do not need a complex spreadsheet. A simple notebook or a note on your phone is enough. ### What to Track - **Move dates:** When you moved the coop and where you moved it from and to - **Pasture condition:** Grass height, bare spots, weed pressure, and manure coverage before and after each move - **Egg production:** Number of eggs per day and any changes - **Feed consumption:** How much feed the birds eat per day or per week - **Bird health:** Any signs of illness, lameness, or abnormal behavior - **Weather:** Rain, temperature, and wind that might affect pasture growth or bird health - **Predator activity:** Any signs of attempted entry, tracks, or lost birds ### How to Use the Records After 4 to 6 weeks, look back at your records. Do you see a pattern of pasture damage in certain spots? Are egg numbers dropping when you move the coop more often? Are you seeing more parasites in wet weather? Use these patterns to adjust your rotation. For example, if you notice that the pasture always looks thin in late summer, move the coop more often during that period or reduce the number of birds. If you notice that parasite problems spike after a wet spell, extend the rest period between rotations. ### Parasite Monitoring Internal parasites are a major concern with pastured poultry. The most common worms are roundworms, cecal worms, and capillary worms. Signs include weight loss, pale combs, diarrhea, and reduced egg production. You can monitor parasites by collecting fresh fecal samples and sending them to a veterinary lab for a fecal float test. Your veterinarian or extension agent can tell you how to collect and submit samples. Do this at least twice a year, once in the spring and once in the fall. If parasite loads are high, your veterinarian may recommend a dewormer. Follow the label instructions exactly. Rotate between different classes of dewormers to prevent resistance. ## When to Call a Veterinarian or Extension Agent Most mobile coop problems are management issues you can solve yourself. But some situations need professional help. Call your veterinarian or extension agent in these cases: ### Sudden Deaths If you lose more than one or two birds in a 24-hour period, call a veterinarian immediately. Sudden death in multiple birds can indicate a contagious disease, a toxin exposure, or a predator problem that needs investigation. ### Respiratory Signs Coughing, sneezing, nasal discharge, swollen eyes, or gasping for breath can indicate respiratory disease. Some respiratory diseases spread quickly through a flock. Isolate sick birds and call for advice. ### Severe Diarrhea Watery, bloody, or foul-smelling diarrhea can indicate coccidiosis, bacterial infection, or severe parasite load. This is especially urgent in young birds. ### Drop in Egg Production A sudden drop of more than 20 percent in egg production over a few days is a red flag. It can indicate disease, stress, or a nutritional problem. Keep records so you know what normal production looks like for your flock. ### Neurological Signs Tremors, twisted necks, paralysis, or birds that cannot stand can indicate serious diseases like Marek's disease, [avian influenza](/knowledge/bacteria/avian-bacteria/avian-influenza-cdc-global-surveillance), or Newcastle disease. Some of these are reportable diseases. Call your veterinarian or state animal health official immediately. ### Reportable Diseases Certain diseases must be reported to state or federal authorities. These include [avian influenza](/knowledge/bacteria/avian-bacteria/avian-influenza-cdc-guidelines-poultry-pandemic-preparedness), Newcastle disease, and Salmonella pullorum. If you suspect any of these, contact your veterinarian or the USDA APHIS office in your state. Do not move birds or equipment until you get instructions. ## Seasonal Management for Mobile Coops The rotation schedule and coop management change with the seasons. Plan ahead so you are not caught off guard. ### Spring Spring is the best season for pasture rotation. Grass grows fast, insects are abundant, and the weather is mild. Move the coop every 3 to 5 days. Watch for muddy conditions after spring rains. If the ground is saturated, move the coop less often or place it on a gravel pad to prevent the pasture from being torn up. ### Summer Summer heat stresses birds. Make sure the coop has plenty of shade and ventilation. Move the coop more often in hot weather because manure breaks down faster and flies become a problem. Provide cool, clean water at all times. Consider moving the coop to a spot with afternoon shade. ### Fall As grass growth slows, extend the rotation interval to 5 to 7 days. The pasture needs more time to recover. Watch for an increase in parasite problems as the weather cools and moisture returns. ### Winter Winter is the hardest season for mobile coops. Snow and frozen ground make moving difficult. Many farmers move the coop to a sheltered spot for the winter and keep the birds in a fixed run with bedding. If you keep the coop mobile through winter, use skids instead of wheels and move it less often. Provide extra insulation and make sure the birds have protection from wind. ## Frequently Asked Questions **How often should I move a chicken tractor?** Move a chicken tractor every 2 to 4 days in warm weather and every 5 to 7 days in cool weather. The exact interval depends on pasture condition. Move the coop when the grass is grazed down to about 2 inches, when manure is visibly building up, or when the birds are scratching so hard they are creating bare soil. In spring when grass grows fast, you can keep birds in one spot longer. In late summer when grass growth slows, move more frequently. **How many chickens can I keep in a mobile coop?** The number depends on the coop size and the design. A standard 4x8 foot A-frame comfortably holds 4 to 6 standard-size hens. A 10x20 foot hoop house can hold 15 to 25 birds. A trailer-mounted coop can hold 30 to 100 birds or more. The key is to give each bird at least 4 square feet of indoor space and 10 to 20 square feet of pasture per day. Overcrowding leads to dirty eggs, aggressive pecking, and rapid pasture damage. **Do mobile coops protect chickens from predators?** Yes, if they are built correctly. Use 1/2 inch hardware cloth, not chicken wire, on all sides. Close all doors at night. Bury the bottom edge of the wire 6 inches into the ground if you have digging predators. Anchor the coop against wind and larger predators. A well-built mobile coop protects against raccoons, foxes, dogs, and birds of prey. A poorly built one does not. **Can I leave a mobile coop in one spot for a week?** You can, but you should not. Leaving a mobile coop in one spot for more than 5 to 7 days defeats the purpose of the system. Manure builds up, parasites multiply, and the pasture gets damaged. If you cannot move the coop at least every 7 days, use a fixed coop with a proper cleaning routine instead. **Do I need a floor in a mobile chicken coop?** No. A floorless coop is the standard design for pasture rotation because it lets birds graze directly and deposit manure onto the soil. A floored coop is easier to clean but does not provide the same pasture improvement benefits. Some farmers use a floored coop with a wire mesh floor to let manure drop through. This works but requires more frequent cleaning. **What is the best material for a mobile coop floor?** If you use a floor, the best options are 1/2 inch hardware cloth or welded wire mesh raised 2 to 4 inches above the ground. This lets manure fall through while keeping the birds off the soil. Solid wood or plywood floors are easier to clean but trap moisture and ammonia. If you use a solid floor, add plenty of bedding and clean it weekly. **How do I move a heavy mobile coop?** Use wheels, skids, or a trailer hitch. Small coops under 100 pounds can be moved by hand with wheels on one end. Larger coops need a vehicle. A trailer-mounted coop moves with a truck or ATV. A skid-mounted coop drags behind a tractor or ATV. If you have to move a heavy coop by hand, use a come-along winch or a set of pipes to roll it. Do not try to drag a heavy coop across rough ground by yourself. **What do I do with the manure left behind after moving the coop?** The manure is fertilizer. It breaks down naturally in the pasture over 3 to 6 weeks. If you want to speed up breakdown, drag the area with a harrow or rake after moving the coop. This spreads the manure and exposes it to sunlight, which kills parasite eggs. If the manure is too thick in one spot, spread it manually before the pasture recovers. ## Related Farming Guides This section will be populated with links to other farming guides on this site.
