As I stated in my intro I’m thinking that the space under my deck would provide a very manageable coop and run. I could hang the coop from the deck joists with chain thereby eliminating legs and then the run would be much easier to rake, clean, etc. I could also reposition the coop without concerning myself with having to stabilize legs or level the coop. The deck is 12’ deep by 40’, but I wouldn’t use all of this space. 4 hens with say a 12’ x 20’ run would live on a reservation. The coop would be 4’ in width providing a 4’ space between it and the wall of the house and the hardware cloth around the edge of the deck. The nest box would protrude from the hardware cloth for easy access. I would frame a door at the opposite end of the run facing the coop. To help camouflage the coop I would plant climbing ivy around the outside of the hardware cloth across the end and around the corner past the coop for 10’ or so. This would provide approx 10’ of unobstructed afternoon sun for the run, but shade the coop end and help control it’s interior temp. And it would also hide the coop and “dress up” the area. Beneath the deck floor joists I would attach fiberglass roofing panels (with appropriate grade) and a gutter to help keep the run dry. I would really appreciate your feedback and suggestions. I only want to build this once. (he said) Next I will design the hanging coop and yes I will also ask you to "sign off" on it! LOL Thanks! Nothing is to scale in this pic except the deck height.
