When we bought this house it had a coop inside an old barn (concrete floor, real walls, a ventilation window covered with hardware cloth, and two doors) I thought this was great but now looking at coop pictures on BYC I think it's too big and there is no way our chickens can keep themselves at all warm. The interior is about 12 X 12 (maybe more) and the ceiling is about 6.5 feet. (about 900 cubic feet). That's a lot of space for 10 chickens, and when I see those smaller coops, I realize those chickens are probably much warmer at night than mine. I worry most about my two oldest girls.....The most recent repost on not spoiling our chickens just reinforces my belief. That coop is small enough for those chickens to warm the space at night. Would it be better for our chickens to make some kind of enclosure around the roosting poles, even if it was just curtains we could close at night?
