Start with salvaged materials and a straightforward design
A functional chicken coop does not require new lumber or expensive hardware. The cheapest route is to use materials you already have or can find free—old pallets, reclaimed wood, wire fencing, and scrap metal roofing. A basic coop for three to four chickens can be built for $50 to $150 if you source materials this way, or $150 to $200 if you buy new supplies at a hardware store.
The simplest design is a wooden box with a wire-mesh run attached. The coop itself—where chickens roost and lay eggs—needs to be predator-proof and dry. The run is the outdoor area where they scratch and peck during the day. You do not need fancy features. Chickens care about shelter from wind and rain, protection from foxes and raccoons, and space to move. Everything else is optional.
Key Takeaways
- Free or cheap materials like pallets, scrap wood, and old fencing can cut your coop cost to $50 to $100 instead of $300 or more.
- A basic coop is a wooden box (4 feet by 4 feet for four chickens) with a hinged roof and a wire-mesh run attached for daytime access.
- The most important expense is hardware cloth (not chicken wire) for the walls and floor, because chicken wire does not stop predators.
- Pallets from stores, construction sites, and warehouses are often free if you ask, and they provide most of the wood you need.
- A coop built in a weekend with basic tools will last three to five years and house four chickens comfortably.
Where to find free or cheap materials
Pallets are the backbone of a budget coop. Stores like grocery chains, hardware stores, and warehouses often give them away because disposal costs money. Call ahead and ask if they have pallets you can take. Avoid pallets marked with "HT" (heat-treated), which is safe; refuse those marked "MB" (methyl bromide), which is a pesticide. Most unmarked pallets are heat-treated and fine for a chicken coop.
Craigslist, Facebook Marketplace, and Nextdoor often have free wood piles, old fencing, and roofing materials from renovations. Habitat for Humanity ReStore locations sell reclaimed building materials at a fraction of retail price. Check local demolition sites or ask neighbors who are doing construction work. A single source rarely gives you everything, but combining three or four sources keeps costs low.
For hardware cloth and fasteners, you will need to buy new. Hardware cloth (a wire mesh with small openings) costs $15 to $30 for a roll large enough to line a small coop. Chicken wire is cheaper but does not stop predators—raccoons tear through it easily. Screws and nails cost $5 to $10. A hinged roof latch and a straightforward door latch are $5 to $10 more.
Basic coop design: dimensions and layout
A coop for four chickens should be at least 4 feet by 4 feet inside, with 3 to 4 feet of height. This gives each bird about 4 square feet of indoor space, which is the minimum for them to not peck each other out of stress. The run (outdoor area) should be at least 8 feet by 8 feet, or 16 square feet per bird. If space is tight, 8 feet by 4 feet works for four chickens if they spend most of the day outside.
Build the coop as a straightforward rectangular box. Use pallets as the frame and walls—they are already the right height and thickness. Disassemble them if needed, or stand them upright and bolt them together. Line the inside walls and floor with hardware cloth, stapling it securely so predators cannot pry it loose. Staple it to the wood so the mesh overlaps the edges by at least 2 inches.
The roof should slope slightly so rain runs off. Use corrugated plastic, old metal roofing, or even heavy plywood covered with a tarp. Attach it with hinges on one side so you can open it to clean inside. A straightforward hook-and-eye latch keeps it closed against wind and predators.
Step-by-step building process
Day 1: Prepare and frame the coop box. Lay out four pallets in a rectangle on level ground. If the ground is soft or wet, place them on concrete blocks or gravel to keep the bottom dry. Bolt or screw the corners together using 3-inch wood screws or bolts. Check that the frame is square by measuring corner to corner—both diagonals should be the same length. Attach a floor made of scrap wood or pallet boards, leaving small gaps for drainage.
Day 1 continued: Line with hardware cloth. Unroll hardware cloth and staple it to the inside of all four walls, starting at the bottom. Overlap each piece by 2 inches and staple every 4 to 6 inches. Staple it to the floor as well, folding it up the walls. This takes time but is the most important step—it stops raccoons and weasels from chewing through.
Day 2: Build the roof and run. Attach two roof panels (plywood or corrugated plastic) to the top with hinges on one side. Add a latch on the other side. Build the run by creating a frame from 2x2 lumber or pallet wood and covering it with hardware cloth or chicken wire. Attach it to the coop with hinges or bolts so you can open it for cleaning. Add a door (a straightforward wooden frame with wire mesh) that you can open and close by hand.
Day 2 continued: Add nesting boxes and roosts. Inside the coop, attach two or three nesting boxes (wooden crates or boxes 12 inches square, filled with straw) to the walls about 2 feet high. Chickens will lay eggs in these. Add a roost—a wooden dowel or branch 2 to 3 inches in diameter, mounted 3 to 4 feet high—where chickens sleep at night.
Common mistakes that waste money or fail
Using chicken wire instead of hardware cloth is the most expensive mistake. Chicken wire has large openings and is thin; raccoons and weasels tear through it in minutes. You will lose birds and have to rebuild. Hardware cloth costs more upfront but lasts years and actually stops predators.
Skipping the floor is another common error. If the coop sits directly on soil, predators dig underneath. Even a straightforward wooden floor with hardware cloth stapled to it stops burrowing. If you cannot afford a full floor, at least bury hardware cloth 6 inches deep around the perimeter.
Building the coop too small seems like a cost saving but leads to stress, disease, and aggression among birds. Four chickens in a 3-foot-by-3-foot coop will peck each other bloody. The extra cost of a 4-foot-by-4-foot frame is minimal compared to replacing injured or dead birds.
Leaving gaps or loose edges in the mesh is how predators get in. Staple every 4 to 6 inches, overlap seams by at least 2 inches, and check the entire perimeter before you bring chickens home. A single loose corner can be fatal.

Tools you will need: a power drill or screwdriver, a staple gun, a tape measure, a level, a saw (hand saw or circular saw), and a wrench or socket set for bolts. If you do not own these, borrow them from a neighbor or rent them from a tool library—many communities have free or low-cost tool libraries.
Maintenance and extending the coop's life
A budget coop built from pallets and scrap wood will last three to five years with basic care. Inspect the hardware cloth twice a year for rust or tears. If you find damage, patch it when ready with a staple gun and a scrap of mesh. Check the roof for leaks before winter and patch any holes with roofing tar or a tarp.
Replace the roost bedding (straw or wood shavings) every two to four weeks to prevent disease. Clean out the nesting boxes weekly. In winter, add extra insulation by stapling straw or old blankets to the inside walls—chickens generate heat and do not need a heater, but they need protection from wind and drafts.
If wood begins to rot, replace the affected boards. Pallets are cheap enough that swapping out one or two is faster and cheaper than trying to repair them. Keep the coop elevated slightly off the ground (on blocks or gravel) so air circulates underneath and moisture does not pool.
Frequently Asked Questions
Can I use chicken wire instead of hardware cloth to save money?
No. Chicken wire is thin and has large openings; raccoons and weasels tear through it easily. You will lose birds. Hardware cloth costs $20 to $30 more but stops predators and lasts years. It is the one place where saving money backfires.
How many chickens can I fit in a 4-by-4 coop?
Four chickens comfortably. Each bird needs about 4 square feet of indoor space. Fewer birds means less stress and fewer health problems. If you want more chickens, build a larger coop or add a second one.
Do I need a run, or can chickens just stay in the coop?
Chickens need outdoor space to scratch, peck, and exercise. A run keeps them safe from predators while they are outside. Without a run, you have to let them roam your yard (and they will destroy it) or keep them confined, which causes stress and aggression.
What is the best roofing material for a cheap coop?
Corrugated plastic panels or old metal roofing are durable and cheap if you find them used. Heavy plywood covered with a tarp works too. Avoid thin materials that sag or leak. The roof needs to shed rain completely so the inside stays dry.
How do I protect the coop from predators at night?
Close and latch the coop door every evening so chickens are locked inside. Use a hook-and-eye latch or a sliding bolt that a raccoon cannot open. Check that all mesh is find and overlapped. Predators are most active at night, so this is the most important time to lock up.
