How Big Should a Chicken Run Be for 4 Chickens

So for 4 chickens that free range, you only need a coop/run area that measures about: 4 by 4 feet (16 square ft). But it is always best to give them as much space as you can. For chickens that will be inside the run all the time (never free ranging), you need to bump that number up to 10 square feet per bird.

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.

How big should coop be for 4 chickens?

The minimum rule of thumb is about 2 to 3 square feet per chicken inside the chicken coop, and 8 to 10 square feet per chicken in an outside run. More square footage is better. Skimping on space requirements for a flock of chickens can cause stress, cannibalism, pecking, and sometimes even death.
