Chicken Coop Basics: Space, Bedding and Predators
A coop is a ventilated box with a lock. Most bought coops are too small and too airtight.
Direct answer: Give each bird 4 square feet inside and 10 in the run, 8–12 inches of roost per bird, one 12x12 inch nest box per 3–4 hens, and ventilation high above the roost. Use hardware cloth, not chicken wire, and a latch a raccoon cannot open.
Space rules
| Element | Dimension |
|---|---|
| Coop floor | 4 sq ft per bird (5 for heavy breeds) |
| Run | 10 sq ft per bird minimum |
| Roost | 8–12 in per bird, 2x4 on edge or 2 in dowel |
| Nest box | 12x12x12 in, 1 per 3–4 hens |
| Pop door | 10x12 in, 12–18 in off the floor |
| Ventilation | 1 sq ft of vent per 10 sq ft of floor, above head height |
Bedding options
- Pine shavings: the default. Absorbent, cheap, compostable. Avoid cedar, which can irritate respiratory systems.
- Straw: good insulation, less absorbent, mats down.
- Hemp bedding: highly absorbent, expensive.
- Sand: easy to scoop, heavy, dusty in dry climates.
- Deep litter: 6–8 inches of carbon material that composts in place — works only if it stays dry.
Predator-proofing checklist
- Hardware cloth (1/2 inch) on every opening, buried 12 inches or with a 24-inch apron.
- Latches: two-step or carabiner — raccoons open simple hooks.
- No gaps above 1/2 inch anywhere.
- Roof over the run to stop hawks and owls.
- Automatic door or a dusk routine.
- No food left out overnight.
- Check for dig marks weekly.
Ventilation without drafts
Chickens tolerate cold far better than damp. Vents should be high — near the roof line — so fresh air enters above the birds and moisture escapes. A coop sealed tight will produce frost on the walls and respiratory disease by February.
Frequently asked questions
Do I need to insulate the coop?
Usually not. Ventilation and dry bedding matter more. Insulate only in extreme cold, and never block vents to do it.
Can I use a plastic storage box as a coop?
For a hospital pen or a brooder, yes. As permanent housing it lacks ventilation and space, and overheats in summer.
How often do I clean the coop?
Remove droppings weekly, replace bedding monthly, and do a deep clean twice a year. Deep-litter systems need turning rather than full replacement.
Build the flock plan first: backyard chickens for beginners and flock size on a quarter acre.
