You have a horse stall sitting empty, and you’re wondering if you could repurpose it for chickens. The good news: horse stalls are actually ideal structures for conversion. They already have solid walls, roof protection, and drainage considerations. With some practical modifications for ventilation, predator protection, and nesting infrastructure, you can transform that unused structure into a thriving chicken home in just a weekend.
How to Convert a Horse Stall into a Chicken Coop
This conversion leverages the stall’s existing structure while adding the specific requirements chickens need: secure housing, proper airflow, safe roosting, and protected outdoor access.
Materials You Will Need
- Heavy-gauge welded wire fencing (1/2 inch or smaller mesh to prevent predator access)
- Pressure-treated lumber for framing roosts and nesting boxes (2x4s and 1x12s)
- Wood screws (2.5 inch and 1.5 inch), nails, and a power drill
- Roofing material or corrugated panels for a covered run extension (optional but recommended)
- Hinges and handles for access doors and clean-out panels
- Sand, shavings, or straw for floor bedding and nesting material
Conversion Steps
Inspect and Repair the Structure
Walk through the stall thoroughly, looking for gaps in walls, broken boards, or sharp objects. Patch any holes larger than 1/4 inch with wire mesh or wood. Check the roof for leaks and repair if necessary. A solid, secure structure prevents predator entry and weather damage.
Secure All Openings with Predator-Proof Fencing
Install heavy-gauge wire mesh over windows, vents, and any openings larger than 1/2 inch. Bury fencing at least 12 inches into the ground around the perimeter if the stall touches earth, or secure it tightly to the base. This stops raccoons, rats, and other predators from entering.
Install Roosts at Appropriate Heights
Build or install horizontal roosting bars 2-3 feet off the ground using sturdy wood poles or 2×4 lumber. Space multiple roosts 12-14 inches apart vertically and 14-16 inches apart horizontally so chickens don’t soil each other overnight. Ensure roosting bars are smooth and splinter-free for bird safety.
Build or Install Nesting Boxes
Create enclosed nesting boxes using wood, with interior dimensions of roughly 12 x 12 x 12 inches per box. Plan for one box per 3-4 hens. Mount boxes 18-24 inches above the floor in a darker corner of the stall. Add sloped roofs to discourage roosting on top, and include a lip at the entrance to contain bedding.
Create a Clean-Out and Access Door
Cut a door opening (at least 18 inches wide) into the lower part of the stall wall for daily access, egg collection, and bedding changes. Install a hinged, lockable door that seals tightly at night. Include a small pop door (6 x 8 inches) with an automatic opener if you want hands-free morning/evening routines.
Improve Ventilation Without Drafts
Ensure air circulation by adding vents high on opposite walls, well above roosting height. Cover vents with wire mesh to keep predators out. Proper ventilation reduces moisture and ammonia buildup, critical for respiratory health. Avoid creating direct drafts across the roost area.
Prepare the Run and Outdoor Access
Attach a covered run or chicken wire enclosure to the stall’s south-facing side, creating a sheltered outdoor space. Use sturdy fencing to extend at least 20 feet out if possible. Cover the top with shade cloth or roofing material to protect from hawks and weather while allowing light and airflow.
Layer Bedding and Test for Safety
Spread 3-4 inches of coarse bedding (sand, shavings, or straw) on the stall floor. Walk the perimeter inside and out one final time, checking for sharp wire edges, loose boards, or remaining gaps. Lock all doors and leave them closed overnight to verify security before introducing your flock.
- Install roosts at different heights so lower-ranking hens can find safe sleeping spots away from dominant birds–this reduces stress and injury.
- Use sand in the run area rather than shavings; it drains faster, stays cleaner longer, and chickens enjoy dust bathing in it to control parasites.
- Add a removable droppings board under roosts to simplify cleaning and reduce ammonia odors–simply slide it out and scrape weekly.
What to Look For in Chicken Coop Materials
- Wire Mesh Size: Use 1/2-inch or smaller welded wire to exclude adult raccoons and rats. Avoid chicken wire alone, as raccoons can tear through it. Hardware cloth or welded wire provides superior predator protection.
- Wood Quality and Treatment: Select pressure-treated lumber for ground contact and rot resistance, or cedar for visible roosts and nesting areas. Avoid treated wood in areas where chickens peck or nest, as chemicals can leach; use untreated pine for interior framing instead.
- Ventilation Capability: Ensure your conversion allows opposing vents at the roof line to create cross-ventilation without drafts. Poor airflow leads to moisture buildup, mold, and respiratory disease, especially in winter.
- Predator Access Prevention: Secure all gaps, bury fencing, and use sturdy latches on doors. Weak points invite predators. Test security by attempting to push or pry every edge; if you can create a gap, a determined predator can exploit it.

Converting a horse stall into a chicken coop transforms unused infrastructure into a productive homestead asset with surprisingly minimal effort. The stall’s existing walls, roof, and drainage already provide the foundation for a superior chicken home compared to building from scratch. By following these eight steps and addressing predator protection, ventilation, and nesting infrastructure, you’ll create a secure, comfortable space that your flock will thrive in for years.
The key to success lies in anticipating predator vulnerabilities, prioritizing airflow, and investing modest time upfront in secure construction. Whether you’re raising layers for daily eggs or broilers for meat, a properly converted stall eliminates the most common problems new chicken keepers face: inadequate predator protection, poor ventilation, and insufficient roosting space. Your weekend project yields a lifetime of functional infrastructure that your future flocks will benefit from long after the initial conversion work is complete.
Frequently Asked Questions
How many chickens can I fit in a converted horse stall?
A standard 10 x 10 foot horse stall safely houses 12-15 medium-sized chickens with proper roosts and nesting boxes. Plan for minimum 3-4 square feet per bird inside the stall and 8-10 square feet per bird in the outdoor run. Overcrowding increases aggression, disease spread, and bedding management challenges.
Do I need to remove the stall’s dividers and doors?
Removing interior dividers opens up usable space, though leaving one divider creates a useful separation for quarantine or separate flocks. Remove the original stall door and replace it with a smaller chicken-access door. Existing wall structures provide excellent predator protection, so preserve them where possible.
What’s the best bedding material for a converted stall?
Coarse sand drains fastest and discourages ammonia buildup, making weekly maintenance easier. Pine shavings offer good absorbency but require more frequent changes. Avoid cedar and oak, which contain oils toxic to chickens. Layer 3-4 inches deep and refresh weekly or when visibly soiled.
How do I prevent predators from digging under the stall?
Bury wire fencing 12 inches deep around the perimeter, extending outward 6-8 inches from the wall base before burying. Alternatively, lay a buried apron of wire mesh 12 inches wide around the structure’s perimeter. Motion-activated lights and removing nearby brush piles also deter nocturnal predators.
Can I use my converted stall for both horses and chickens seasonally?
Seasonal sharing requires removable infrastructure (nesting boxes, roosts) stored when horses occupy the space. Thoroughly clean and disinfect between uses to prevent cross-species disease transmission. Many homesteaders find permanent conversion more practical, as horses and chickens have conflicting spatial needs and behavioral patterns.
