What You Need to Build a Coop for Six Hens
A coop for six hens needs to be at least 24 square feet of interior floor space—that is 4 square feet per bird, the minimum that keeps them from fighting and developing stress behaviors. The structure itself is a wooden frame with wire mesh walls, a solid roof, a door you can lock, and nesting boxes inside where hens lay eggs. You do not need to be a carpenter; the frame is made from 2-by-4 lumber and plywood, fastened with screws and hinges.
The coop sits on the ground or on a raised base, depending on your yard and predator pressure. A ground-level coop is simpler to build but needs a buried or skirted perimeter to stop raccoons and foxes from digging underneath. A raised coop (12 to 18 inches high) keeps predators out more easily and makes cleaning easier, but costs more lumber and takes longer to assemble.
Most backyard builders finish a basic 4-by-6-foot coop in a weekend. The total material cost ranges widely depending on whether you use new or reclaimed lumber, but budget for lumber, hardware cloth (the wire mesh), hinges, a door latch, and roofing material. Do not use chicken wire alone—it tears easily and does not stop determined predators. Use hardware cloth, which is a heavier wire mesh that resists chewing and clawing.
Key Takeaways
- A coop for six hens needs at least 24 square feet of floor space inside, plus a separate run if the hens will not free-range during the day.
- Build the frame from 2-by-4 lumber, cover it with hardware cloth (not chicken wire), and add a solid roof to keep rain and predators out.
- Include at least two nesting boxes inside where hens can lay eggs, and a roost bar where they sleep at night.
- Predator-proof the coop by burying hardware cloth 12 inches deep around the perimeter or raising the coop 12 to 18 inches off the ground.
- Plan for a door you can lock at night and a ventilation opening near the roof to prevent moisture and ammonia buildup.
Choosing Between a Ground-Level and Raised Coop
A ground-level coop sits directly on the earth. It is cheaper to build because it uses less lumber, and it is easier to move if you have a small yard. The downside is that predators can dig underneath—raccoons, foxes, and groundhogs will tunnel under a coop if they smell hens. To stop this, you must bury hardware cloth at least 12 inches deep around the entire perimeter, or lay it flat on the ground and extend it 2 feet outward, then cover it with soil or mulch. This takes time and materials but is effective.
A raised coop sits on legs 12 to 18 inches above the ground. Predators cannot dig underneath, and you can see underneath easily to spot problems. Cleaning is easier because you do not have to bend as far. The trade-off is that you need more lumber for the legs and frame, and the structure is harder to move once built. A raised coop also needs a ramp or ladder for hens to climb in and out, which adds another small build step.
For most backyards, a raised coop is worth the extra cost and effort. It is safer, easier to maintain, and lasts longer because the wood does not sit in damp soil where it rots. If you have a very small yard or plan to move the coop often, a ground-level coop with buried hardware cloth is a reasonable choice.
Building the Frame and Walls
Start by cutting your lumber to size. For a 4-by-6-foot coop, you need four corner posts (2-by-4s, about 3 feet tall), four long beams (2-by-4s, 6 feet long), four short beams (2-by-4s, 4 feet long), and plywood for the roof and any solid walls. Lay out the four corner posts on a flat surface and connect them with the long and short beams using 3-inch exterior screws—two screws per joint. This creates a rectangular frame.
Once the frame is square and sturdy, cover the sides and front with hardware cloth, stapling it to the wooden frame every 4 to 6 inches. Overlap the seams by at least 2 inches and staple the overlaps too. Leave one side or the front as a door—you will hinge a wooden panel there so you can reach inside to collect eggs and clean. The back wall can be solid plywood if you want to block wind, or it can be hardware cloth like the rest.
The roof is the most important part for keeping rain out. Use plywood sheathing covered with roofing felt and shingles, or use corrugated plastic panels that let light in. The roof should overhang the walls by at least 6 inches on all sides so rain does not run down the sides and soak the bedding. Slope the roof slightly so water runs off rather than pooling.
Adding Nesting Boxes and Roosts
Inside the coop, hens need two things: a place to lay eggs and a place to sleep. Nesting boxes are small enclosed spaces, usually made from a wooden crate or a plywood box about 12 inches wide, 12 inches deep, and 12 inches tall. For six hens, build at least two boxes—one box per three hens is the standard. Line the bottom with 4 to 6 inches of bedding (wood shavings, straw, or shredded paper), and hens will lay their eggs there. Mount the boxes on the wall about 2 feet off the ground, or lower if your hens are older and have trouble jumping.
A roost bar is a wooden dowel or branch where hens perch to sleep at night. Hens naturally roost—they climb up to sleep as a defense against ground predators. Install a roost bar 2 to 3 feet off the ground, running the length of the coop. A 2-by-2 piece of lumber works well, or a branch 2 to 3 inches in diameter. Space multiple roosts 12 inches apart if you have room. Hens will poop while roosting, so put a droppings board (a sheet of plywood) underneath to catch it and make cleaning easier.
The floor of the coop should be covered with 4 to 6 inches of bedding—wood shavings, straw, or sand. This absorbs moisture and droppings, keeps the hens warm, and gives them something to scratch in. Change the bedding weekly or as it gets wet and soiled. A damp coop breeds disease and parasites, so ventilation and dry bedding are critical.
Ventilation and Predator-Proofing
Hens produce a lot of moisture and ammonia from their droppings. Without ventilation, the coop becomes humid and smelly, and respiratory disease spreads fast. Cut a ventilation opening near the roof on at least two sides of the coop—these can be straightforward rectangular holes covered with hardware cloth to keep predators out. The opening should be at least 1 square foot per side. In winter, you want air to move without creating a draft at the roost level, so place vents high on the walls.
Predator-proofing is not optional. Raccoons are smart and persistent—they can open straightforward latches and tear through weak wire. Use a slide bolt or padlock on the main door, not a hook-and-eye latch. If you have a separate run (an outdoor enclosure attached to the coop), lock that door too. Check the entire perimeter for gaps larger than a quarter-inch—rats can squeeze through anything bigger. If you are raising the coop, make sure the gap underneath is less than a quarter-inch, or cover it with hardware cloth.
Bury hardware cloth 12 inches deep around the perimeter if your coop is ground-level, or extend it 2 feet outward and bury it 6 inches deep. This stops digging predators. If burying is not practical, lay hardware cloth flat on the ground around the coop and cover it with mulch or soil—predators will feel it and move on to easier prey.
Adding a Door and Access Points
The main door should be large enough for you to reach inside comfortably—at least 18 inches wide and 24 inches tall. Hinge it on one side and install a slide bolt or padlock on the other. Make sure the door closes tightly; a gap of even half an inch can let a weasel inside. Test the door by trying to wiggle it—if it moves, tighten the hinges or add a catch on the bottom.
If your coop has a separate run (a fenced outdoor area), install a smaller pop door between the coop and the run. This is usually a 10-by-10-inch opening with a sliding wooden panel that you can close at night and open during the day. You can automate this with a timer-operated door opener, but a manual slide is simpler and cheaper. The pop door lets hens go outside during the day and retreat to the coop at night without you having to open the main door.
Make sure you can reach every corner of the coop for cleaning. If the coop is raised, add a ramp with cleats so hens can climb in and out. The ramp should be about 3 feet long and slope gently—hens are not good climbers and will not use a steep ramp.
Bedding, Cleaning, and Maintenance
Start with 4 to 6 inches of bedding on the floor. Wood shavings (pine or aspen, not cedar or oak) are the most common choice. Straw works but is less absorbent. Sand is excellent for dust baths and drainage but is heavy to change. Whatever you choose, plan to change it weekly or more often if it gets wet. Wet bedding breeds disease and parasites, and ammonia from urine burns hens' eyes and lungs.
Clean the nesting boxes weekly by removing soiled bedding and replacing it with fresh material. Wipe down the roost bar and droppings board weekly too. Once a month, do a deep clean: remove all bedding, scrub the floor and walls with a brush, and let the coop dry before adding fresh bedding. If you notice mold, ammonia smell, or sick hens, clean more often.
Check the coop regularly for damage. Look for loose boards, torn hardware cloth, gaps around the door, and signs of predator activity (scratches, bite marks, holes). Repair damage when ready—a small gap today is a dead hen tomorrow. In winter, make sure the coop does not get too cold; hens can handle freezing temperatures if they are dry and have good ventilation, but ice and dampness are dangerous.
Frequently Asked Questions
Do I need a separate run, or can the hens just free-range?
A separate run (a fenced outdoor enclosure) protects hens from daytime predators and keeps them out of your garden. If you have a find yard with no predators and do not mind hens scratching up your plants, free-ranging works. Most people use a run so they can let hens outside safely while they are at work.
What is the best bedding material?
Pine or aspen wood shavings are the most popular because they absorb moisture, are affordable, and are straightforward to change. Avoid cedar and oak, which are toxic to hens. Straw is cheaper but less absorbent. Sand is excellent for drainage and dust baths but is heavy to move.
How often do I need to clean the coop?
Remove soiled bedding and droppings from the roost area weekly. Change all bedding weekly or more often if it gets wet. Do a deep clean (scrub and disinfect) once a month. A damp, dirty coop spreads disease fast, so do not skip cleaning.
Can I use chicken wire instead of hardware cloth?
No. Chicken wire is thin and tears easily—raccoons and foxes can claw through it. Hardware cloth is much stronger and resists chewing and clawing. It costs more but is worth it for predator protection.
What temperature is too cold for hens?
Hens can survive freezing temperatures if they are dry and have good ventilation. The real danger is dampness and ice. In winter, focus on keeping the coop dry and free of drafts at the roost level. Provide extra bedding for insulation, and break ice in the water regularly.
