Hi! My name is Bella and this is my first post on this website. I am determined to build my own coop, sheerly to save money. I live in Durango, CO, so it probably needs to be insulated, I'm guessing? How do you insulate a coop? Would stacking straw bales around it be sufficient? How big should it be for 5-7 girls? I'd love some ideas. I need the coop to be very simple, because I need to build it fast, and also I'm fairly small. I'd like to also have an outside run attached to the coop. It all needs to be VERY predator proof, because we have lots of critters around here. Thanks for your time!
