    Our coop is 8x8x8 and houses 5 New Hampshire hens and 2 White Rocks (for now!). The door and window are on the south side; the nest boxes are mounted on the east interior wall. The north and south walls stop short of the roof by about 6” for ventilation (that is, the studs go all the way, but not the sheeting). It’s cobwebby up there, but I’ve never had ammonia buildup.

    My Q is this: how many of the 6”x16” spaces can we safely close for the winter? I noticed last night that the cobwebs had frost on them from heat/moisture rising from the girls. They obviously need ventilation, but I want to conserve heat wherever possible. A clear, windy night here can be -10deg. /-50 wind chill.

    Also, what should I feed them while grass is hard to find?

    I think i'd cover the north side spaces and leave all the south facing space open
