Hello all. I'm new to chicken raising and am planning on building my own coop. Before proceeding onto building, I'd like to get some information: Is 1m by 1m (plus a 1m by .5m nesting area) ok for 4 chickens? Is 1m too high for the "living room" area? Can I insulate the coop by making the walls a sandwich of plywood, insulation, and more plywood? Thanks in advance. Any comments, related or non-related tips, and general advice are greatly appreciated.
