We are midway through finishing the coop and having a discussion about how many of the windows should open. I want one on each side to open. My husband says two windows total are enough. The window size is huge - 27" x 32", will have 1" hardware cloth, and the coop size is 7 x 7 without the nesting boxes - 7 x 10 with nesting boxes. We are at 3500 ft elevation so extreme heat is rarely an issue, and as you can see, the coop is nested in some trees. The 10 x 30 ft run will go back into the woods. Chick(en)s will free range when possible. What do you think?
