Since we live in Montana and get a lot of snow and cold,(snow on the ground for 4-5 months) we had to insulate and decided to make a roof over the enter run as well. We got our ideas from this forum and also by looking at some coops at a farm store in Missoula. We broke ground on Mother's day and just finished today. We still need to do the permanent electric and also add trim to the windows and door. The total size of the coop is 5 X 9 including the nesting boxes and the run is 8 X 16. So glad to have found this forum and site. Really helped us out a lot!!
