Hi all, I'm new to this and have 10 chicks coming in a couple weeks - 6 Plymouth Rocks and 4 Rhode Island Reds! Anyway, I have an area in the bottom of my barn that is sectioned off into a 10 X 14 space that I'd like to convert into a coop. It has one south west facing wall and one northwest facing wall, both of which I figured I'd insulate with foam board and cover with plywood since it gets bitter cold here (central Vermont) in winter. I'm also building a 4.5 X 10 foot roost platform/dropping pit 18" off of the ground. I'm worried though that 10 X 14 might be too big of an area for the birds to keep warm in during the winter? Am I just being neurotic, which would be bad since the little ones haven't even arrived yet. Thanks in advance.
