Very cute, original coop. With all those spaces in the walls (easy to see on the i side pictures) though I am afraid it is rather drafty. I would definitely put some plywood to cover the inside walls. Also, if the window stays open for ventilation (which it should) you want to use hardware cloth, not chicken wire (same for the run). Chicken wire keeps chickens in, but doesn’t keep predators out - it is too weak. 1/2” hardware cloth is much more protective, secured with washers or between wood boards - those little racoons are strong and will pull staples right out of the wood. Oh and the cinderblock foundation is looking a bit precarious to me, but maybe that’s because we have earthquakes… A good wind gust, though, might knock the coop of its foundation… or a few critters tunneling under it.
