Hi maryboland I too live at 7000 ft in the Northwest Colorado and I think we have very similar coops. I designed and had a local man build it for me since I am not gifted with hammering skills. I too have a enclosed house and then an enclosed indoor 'run'. We used the chicken wire and plastic only for the purposes of year round dirt for bathing, dry place to stay from wind and snow. Ours is lean to in style with the face of the coop towards the south for the solar. I also deep mulch which I did not know I did till I read a forum that called it that and it really does work in Colorado expecially with the DE for the order. Just need new nesting boxes, currently using large flower pots drilled into the walls. Great if you have unlimited space but I am alway wanting more hens and so space is a premium. Good luck sounds great.
