How Much Space Do My Chickens Need?

 

Chickens will be happier and healthier if they are let out during the day to forage. At night, they need protection against predators, so they should be kept in a chicken coop or shelter.  The proper size of the coop depends on how many birds you have, what size they are, and whether you let them out to forage during the day or keep them confined to the coop.

If the coop is too small, manure will build up quickly in it, and ammonia levels in the air can become quite high. This is not good for you or your chickens. Chickens will also tend to peck each other more, and they will be more subject to disease. It’s best to make sure your chickens have plenty of coop space.

Below, we give the minimum number of square feet needed per bird.  To determine the what size your coop needs to be, multiple that number by the number of birds that you plan to house in the coop.

Heavy Breeds

For heavy breeds, like Barred Rocks or Buff Orpingtons, if you let your chickens out to forage during the day, then the coop that you put them in at night should have at least 4 square feet of space per bird.  Thus, a 4′ by 8′ coop would be adequate for about 8 birds.

If you keep your chickens confined to the coop at all times, then you should provide 10 square feet per bird. In this case, a 5′ by 10′ coop would be adequate for 5 birds.

Light Breeds

For lighter breeds, like the White Leghorn, chickens that are allowed to forage outside during the day should have at least 3 square feet per bird, so a 4′ x 8′ coop could house 10-11 birds.

Chickens that are confined should be given at least 7 1/2  square feet of space, so a 5′ by 10′ coop would be big enough for about 6 chickens.

Bantams

Bantams, being smaller, don’t need as much space per bird.  This is one reason they are popular in backyard flocks. 2 square feet per bird is adequate if they are allowed daytime forage, so a 4′ by 8′ coop could house 16 bantams.

We recommend a minimum of 5 square feet per bantam if they are kept confined, so a 5′ by 10′ coop could contain 10 bantams.

    Do chickens need extra heat when the temperature gets below freezing?

    At what age or size will the chickens be safe to let outside to forage? We have a number of barn cats that have shown great interest in the chicks.

    • Matthew says:

      Normally, domestic cats will not harm fully mature chickens, but we have heard of feral cats harming even fully grown chickens. Your cats, being barn cats, might tend to be more aggressive than the “average” domestic cat. You’ll have to make the determination as to the age at which to begin letting your growing chickens begin free ranging.

    Is this just for the coop/run or does it include the hen house too? We have a coop, which they are always in which is 48 sq ft., plus a hen house that is above it, which they have access to during the day and sleep in at night which is 24 sq ft. We have 6 lg breed hens.

    • Matthew says:

      Sheri, you would use the combined square footage of the two areas together, since they have access to both: 48+24 = 72 square feet. This is 9 square feet per hen, which is close to our recommendation of 10 square feet per bird for confined chickens.
