Based on what I've read on BYC so far, it seems that this coop has inadequate ventilation. There is only 1 vent above the window at one end of the coop. NONE of the windows open. They are nailed in and caulked. See where the roof meets the side wall? There's a gap there that goes under the eaves and is closed off. I'm thinking that maybe we can redo the eaves to include an opening the entire length of the coop in front and back to allow for roof line ventilation. We also need to see how we can modify the windows to allow them to open outward from the bottom. I'm clueless here.
