What Size Coop Do I Need For 20 Chickens?

You need a coop of at least 40-80 square feet for 20 chickens. This allows each bird with between 2 and 4 square feet of space, each, which is commonly accepted as an optimal amount per bird.

If you are looking for more precise coop dimensions, a coop of at least 6×8 is generally a good size.

That will afford your birds with a little extra space to roam, as it can house up to 24 birds as per the recommended spatial requirements.

That being said, if you do intend to add to your flock, you may want to consider an 8×8 coop, which comfortably houses up to 32 chickens.
