Mine that I'm building right now is an 8x8 shed that we are modifying. 10 hens currently with plans to add. My prior was only about 4x6 and houses 14 hens at my max, but 12 did better in those dimentions for us. Our temps are about 20-120 so heat so more three worry here. Sad long as there is open access to the chicken yard i think 8 would be fine and you can do boxes on the ground for more roost space
