Hi! I'm considering raising chickens. There's an old tool shed in our backyard that I want to convert into a chicken coop. It's got about 7' X 11' of floor space, and the roof is 8' high at the highest point. I live in eastern Idaho, where it is very cold and very windy in the winter. My main concern is whether or not I need to insulate it, and how much insulation I need, but any other suggestions for a first-timer would be appreciated. Thanks in advance!
