We're framing out the coop and are deciding important things. The coop (4x4) is attached to a run and will be beneath a higher corrugated roof (so no worries about rain). I was thinking of making the half the coop roof hardware cloth instead of wood to let in light and fresh air, but I'm not sure this will be warm enough in winters (~30 F) to trap the rising warm air vs. traditional side vents. I do feel it will help with condensation buildup and fumes but don't have enough experience to say if that is actually true. Yes/no/maybe?
