Chicken Housing tools: what they help with

These calculators size your chicken's living space: the minimum and recommended dimensions, how much bedding or substrate to buy and what fits in the space you have. Too little space is one of the most common welfare problems in pets. The right size gives a chicken room to move, rest and behave normally.

What to know about housing and enclosure size for chickens

Allow roughly 0.4 square meters of coop floor and 1 square meter of run per bird, with 20-25cm of roosting bar each and one nest box per three to four hens. Predator-proofing must include a dig-proof skirt. Target humidity is around 40-60%.

A practical tip

Treat the minimum as the floor, not the goal. Bigger is almost always better, especially for active or social species.

Chicken care rarely sits in one box. You may also find these useful: chicken age tools, chicken behavior tools, chicken breeding tools and chicken cost tools. Or see every chicken tool in one place.

Housing tools for other pets

The same kind of tool exists for other species, each using that animal's own reference data: duck housing, goose housing, quail housing and turkey housing.
