Nice set up. I am concerned that you used chicken wire to enclose the run. Chicken wire keeps chickens in , but does NOT keep predators out!! I am also surprised that the chickens don't fly into the house through that open cat window! LOL. Your chicken coop needs some more ventilation. Perhaps cut out an opening and the cover it in hardware cloth ( to keep predators out and chickens in). You could use the cut out part to attach to a hinge or two and use it as a shutter if it gets cold where you are. Thanks for sharing your coop and ideas.
