How much space do chickens need? This is a question we get a lot, for various applications including nesting box space, yard space, run space, and coop space. While there is no magic number, there are some general guidelines that may be helpful for you to follow to keep your birds happy & healthy.

What factors may impact how much space a chicken needs?


If you have a bantam or other small breed, you will need less space than folks who have giant breeds.


If you have a moody (or especially broody) bird/breed, they may need more space than your well-tempered hens.

Silkies are known to be especially docile, and thus would do well with less space. Brahmas, who are well known for being aggressive, would not fare well with minimal space. Apply these principles to your flock to adjust how much space they may need.

Plus, just like most animals, chickens have individual personalities. So, knowing your birds, make sure to account for their personalities when considering space.


This is especially pertinent for folks who live in cold winter climates.

People who live in the Southeast will lock up their birds less than Northwest farms who get lots of snow. If you know your chickens will be spending a lot of time in the coop, consider providing more space than is ‘necessary’ so they don’t get stir crazy in the winter months!

How much space do chickens need in a nesting box?

According to this article by the University of Georgia, nesting boxes should be 12 inches by 12 inches:

Boxes 12 inches by 12 inches half-filled with straw or other clean litter material are ideal. One nest box for every four to five hens is adequate. Raise the boxes about 2 feet above the ground and place a perch about 4 inches in front of each box so hens have a place to land before entering the nest.”

How much space do chickens need in the coop?

According to this article by the University of Georgia, it is best practice to provide 3.5 square feet of floor space for each bird:

“…the minimum space required per bird depends on the type or breed of bird you select, and will range from 3/4-1 square feet for smaller breeds to 3-4 square feet for turkeys. A good rule of thumb is to provide 3-31/2 square feet of floor space for each bird you intend to keep for egg production.”

How much space do chickens need for their run?

According to this article by Poultry.Extension.Org,

A minimum of  10 square feet/hen outdoor is recommended. Such outdoor access densities are not practical in urban settings. Smaller sized runs are possible but the management of the outdoor run is key. It will quickly be denuded of any plant material and could become muddy during wet weather. This would make the outdoor access more an exercise yard rather than a pasture area. It is important that the run is located in a well-drained area.”

How much drinking and feeder space do chickens require?

According to this article by the University of Georgia, chickens require 1 inch of drinking space and 4-6 inches of feeder space.

What are the consequences of not providing enough space to chickens?


If not given enough space, bullying (such as excessive pecking & feather pulling) can become an issue. This is because without enough space, hens will get stressed. The bullying is a way of acting out in response to this stress.


If your flock gets overcrowded enough, it can become a breeding ground for lice & mites. Being very close together makes it easy for these pests to jump from hen to hen, infecting the lot of them.

Egg Laying Issues

If your hens don’t have enough space to lay their eggs somewhere specific, you will likely start to find a lot more broken eggs. This is because they will lay anywhere they can find the space to do so, not necessarily somewhere soft and cushy. Broken eggs leads to the habit of egg eating, which is annoying to deal with and should be avoided.


In conclusion, your hens will thank you for taking into account just how much space they need to thrive. Giving chickens enough space in the coop, run, and nesting box not only helps you by reducing vet visits & lost eggs, but it will also help them live happier, healthier lives.
