Most chicken keepers start with free coop plans they find online. They print them out, feel confident, and set Saturday aside to build. Then they get to the hardware store and realize the plans have no materials list—or worse, they’re missing half the stuff they actually need.
You end up making four trips to Home Depot, spending way more than you budgeted, and your weekend stretches into Sunday night. We’ve been there. That’s why we built this guide: not just the plans, but the exact materials list you’ll actually need, with current 2026 prices so there are no surprises. For the full range of designs, see our complete chicken coop plans guide.
A real materials list isn’t just a nice-to-have. It’s the difference between a smooth weekend build and a frustrating scramble.

Why Most Free Coop Plans Fail You
Here’s what typically happens with free plans online: the PDF shows you a nice drawing, maybe some dimensions, and a vague “materials needed” section that says “lumber, screws, and wire.” That’s it. No quantities, no specs, no hardware options. So you make your best guess, buy what seems reasonable, and then you’re halfway through cutting and realize you need hinges—but not just any hinges. You need heavy-duty ones that won’t sag.
The worst part is the ripple effect. You skimp on the roofing material, it leaks after the first heavy rain, and now your coop reeks and your birds are stressed. Or you buy interior-grade plywood for the nesting boxes, and it starts rotting after one season. A complete materials list prevents all of this. Use our free plan quality checklist to evaluate any plan before building.
What a Complete Materials List Actually Includes
A real materials list breaks down into categories:
- Lumber: Posts, beams, framing studs, joists, and trim. Not just “some 2x4s” but “(4) 2x4x8 pressure-treated.”
- Plywood: Walls, floors, roofs, and nesting boxes. Exterior-rated (CDX or better) holds up to weather.
- Hardware cloth: 1/4-inch or 1/2-inch gauge, with specific square footage.
- Fasteners: Exterior screws, not interior drywall screws that rust in months.
- Hinges & latches: Heavy-duty stainless steel, predator-proof.
- Roofing: Corrugated metal, polycarbonate, or shingles with specific quantities.

Where to Buy Each Item
Home Depot: Solid for lumber, plywood, and most fasteners. Good selection of hinges and hardware cloth.
Lowe’s: Similar pricing to Home Depot. Wider selection of roofing options.
Tractor Supply: Excellent hardware cloth selection and competitive tool prices.
Amazon: Best for hardware, fasteners, and hinges in bulk.
Local lumber yards: Often beat big-box pricing on quality lumber. They’ll cut to length for free.
Our recommendation: buy lumber at Home Depot or local lumber yard, hardware cloth at Tractor Supply, fasteners at Home Depot or Amazon, and roofing at Lowe’s.
Mistakes to Avoid When Buying Materials
- Using interior plywood for floors or nesting boxes. Interior plywood starts delaminating after 6–12 months. Exterior plywood (CDX rated) costs $5–10 more per sheet and lasts 5+ years.
- Buying thin or large-mesh hardware cloth. 1-inch mesh lets snakes and raccoons through. Use 1/4-inch, 16-gauge minimum.
- Skipping pressure-treated lumber for ground contact. Regular lumber rots in 2–3 years. Pressure-treated lasts 15–20 years.
- Buying cheap hinges. A $3 hinge sags within a season. Spend $7–12 on stainless steel strap hinges.
- Using regular screws instead of exterior screws. Regular drywall screws rust in 6 months.
- Pressure-treating the roost bars. Don’t use treated wood on surfaces where birds sit. Use regular cedar or pine for roosts.
How to Save Money Without Sacrificing Quality
- Buy dimensional lumber in bulk—price per board drops about 10%
- Shop end-of-season sales (late August/early September)—15–25% off
- Paint or stain yourself instead of hiring out
- Use standard lumber sizes instead of custom cuts
- Buy hardware cloth in bulk—50-foot roll is cheaper per sq ft
- Make nesting boxes from scrap plywood
- Rent a circular saw and jigsaw instead of buying ($10–15/day)
