How Big a Chicken Coop Do I Need?
Getting coop size right keeps your hens healthy, calm and laying — and prevents the mess, broken eggs and bullying that come from crowding. Use our free Chicken Coop Size Calculator below: enter how many chickens you have and their breed size, and we'll work out the coop floor space, run area, number of nesting boxes and roost length your flock needs. The guidelines are built for Australian backyards — heat, foxes and all. Once you know your numbers, browse our chicken coops and nesting boxes to find the right fit.
🐔 Chicken Coop Size Calculator
Find the right coop floor space, run size, nesting boxes and roost length for your flock — built for Australian backyards by Pets Gear.
Rules of thumb used: coop floor ~0.25–0.55 m² per bird (by breed size), run ~1–2 m² per bird, 1 nesting box per 3–4 hens, and ~20–30 cm of roost per bird. Heat, flock dynamics and lockdown time mean bigger is always better.

Choosing the Right Coop Once You Know Your Size
Your calculator result is the practical minimum — bigger is always better for happy hens. A few rules of thumb:
- Coop floor: roughly 0.25–0.55 m² per bird, depending on breed size.
- Run: at least 1–2 m² per bird; go larger if they can't free-range daily.
- Nesting boxes: 1 per 3–4 hens (hens share favourites, so you don't need one each).
- Roost: about 20–30 cm of perch per bird, set higher than the nesting boxes.
