OK i have a coop that is 4X8 with a slant top that will go from 6 feet high to 4 feet high. How many hens could i keep in it. I do have a run so they get out and play. Reason for the ? is im going to be moving them soon and the winters are a big worse then what i have here. Even if it is only 30 min away. But in the winters past they do not go out in the snow. I open the door to let them rome but they want no part of it. I have 5 now. How many should i have so they can keep warm in the cold winter....Here in Vermot........jim
