Hi, Ive been looking at coop designs for a while and I am just now starting to get a good idea of what i want to build. I live in the North East and as some of you know we can have some cold winter days. So what I'm getting at is I would like to build a coop with 1/2 plywood on the inside with T-11 on the outside with a foam insulator in between. I work in the construction field and this is used all the time . But I have yet to see it on any coop. It would help keep warm in the winter and cool in the summer or am i wrong? Please let me know if I'm missing anything. Thanks
