Hi all! We are building a new coop and have decided to use metal for the roof and the siding. I am just wondering if anyone has done this before? We live in Northern Michigan , so winters can get a little rough. It’s very large. I plan on have three separate coops, a brooder and a storage area. Just framing those in with wood and chicken wire and what not. So I guess I am wondering if I should insulate it or leave it be. Or use metal on the inside as well.
