Hi all. I'm converting a 6'x6'shed into a chicken coop. Our winters get to -40f (live north of Duluth MN...brrr) I have no idea what I'm doing, but determined to get approx. 6-8 layers in the shed. Do any of you have any pointers regarding heating, ventilation, or layout? Any feedback would be rockin'. I found a 14"x 30" window that opens that I will put on the S side, as well as ventilation on the N side. I haven't insulated yet and was wondering what insulation u used, along with ventilation advice etc.. specific to a really really cold place like northern MN (Palo, Mn). Again any advice would be greatly appreciated! I'm going to get my chicks in like 1 1/2 weeks,the clocks a tickin'. Have a great day everyone!
