How many chickens will a 4x4 coop hold?

Chickens require around 2 square feet of space inside a coop, and about 10 square feet of space in a run. A 4x4 coop provides 16 square feet of space, so it could comfortably house up to 8 chickens. However, it is important to consider the breed and size of the chickens when determining how many to house in a coop, as some breeds require more space than others.
