What size henhouse do you need to keep 10 hens?

For 10 hens, a henhouse should ideally provide at least 3 to 4 square feet of space per bird, resulting in a total of 30 to 40 square feet. Additionally, ensure there is adequate nesting space, with 1 nesting box for every 3 to 4 hens, and proper ventilation and roosting areas. It's important to consider outdoor space as well, allowing 10 to 15 square feet per hen in an enclosed run.
