We have to move our chickens because, even though they're happy in their wood-store-turned-coop, we are going to take down the building because the forest service says it's too close to the residential building.In the long run, it is good because the current coop, while comfortable, leaks and got pretty wet in this winter's storms here in the Pacific Northwest. The new coop is a building which is smaller but adequate. It is dark, though. The front door is glass (faces east) and there's a space between the roof and the walls which will hopefully provide sufficient ventillation, but that's it for light. Do they need more light than that? They're outside most of the day.
