How much room do chickens need Calculating coop size
Are you wondering how much space you need to get chickens? You’ll be glad to know that most suburban blocks are big enough for a flock that will keep a small family in eggs for most of the year.
But you also need to calculate chicken coop size. Your chicken coop size will determine how many chickens you can keep in the pen.
(:1f414:) What is the the short answer to how much room chickens need?
Most chicken-keeping resources recommend a minimum of:
- 1m2 coop space per chicken
- 3m2 run space per chicken
- 14 cm roost space per chicken
However, these recommendations are the bare minimum. The more space chickens have, the happier and healthier they are. And the happier and healthier your birds are, the less work they are for you!
We would never have less than 1m2 coop space per bird (although commercial layers are stocked at 7 birds/m2 minimum!). And we’d only have 1m2 if the birds free-ranged all day and were let out early each morning.
However, there are a range of factors that can increase and decrease the amount of space that chickens need in a pen. Read the long answer for the nitty-gritty on space requirements and calculating chicken coop size.

Chickens descended from jungle fowl. Wild jungle fowl tend to have a range that averages about 2 acres per bird. However, the birds still spend most of the day in small groups and visit regular spots to rest, forage and dust-bathe.
Because domestic chickens aren’t relying on their coop or run to provide all of their food, chickens don’t need 2 acres each. Luckily! But the more room chickens have, the happier they tend to be. But there are a lot of other factors that can influence space requirements as well.
Your chickens may need less room if they:
- Are a small breed like bantams or silkies
- Get on well (this is most common in flocks of 2-3 birds)
- Free-range and are only in the coop to nest and roost
- Are let out at dawn every morning (We love automatic doors!)
- Have lots of in-pen amusements such as swings, toys, mirrors, cabbage piñatas etc
- Have places to escape from bullies, hide and forage
- Are pets that get a lot of human attention
- Are rescue birds from a commercial laying operation (they’ll be used to living at 7 birds/m2 minimum, so a whole metre each would feel like a palace!)
Chickens may need more space if:
- They are a large or adventurous breed
- You have a mixed flock
- You keep a rooster
- Your birds tend to participate in bullying behaviours
- You don’t have many toys or amusements
- You don’t have much vegetation in your run, for example if it is just grass
- Your chickens forage for part of their diet
Chickens always need:
- Enough perch space
- Enough nesting boxes (1/4 hens minimum)
- Ample space for dust-bathing (as they will all want to bathe at the same time of day)
- Ample, separated areas of shade – in a run that is mostly sunny, birds tend to spend all day in the shade available, which can lead to bullying
In most flocks a couple feeders and drinkers will be needed so that all birds have ample access to food and water, in particular those who are lower on the pecking order.
As all chicken keepers know, once you start you can't stop. So when calculating chicken coop size, plan for your flock to expand in the future. The easiest answer to the question of how much room chickens need is: as much as possible!
Happy chicken keeping!
