My wife and I recently picked up a second hand coop for a couple that no longer hand chickens and wants to see their coop get put to good use. We had to break down the coop for transport and have yet to being the reassembling process. The area we've designated for the coop is 18' X 24' and the coop will be taking us a 6' X 12' area. I know we'll be fencing in the unused area. My biggest concern is should i insulate the walls and ceiling as I live in northern Vermont and our winters do have times where the temps can plummet to -20 to -30.
