I am thinking of converting a metal shed. I live in central Illinois. The weather..... Well your guess is ad good as the weather man. Sometimes we are barely below freezing sometimes we are - 20. Summers we can be in the 90s or 115. Who knows. My question is do I insulate? It will be completely shaded. I was planning on leaving the front open (like in the picture ) until and making the run that attaches to he front predator proof. I see plans for open air coops in the winter with snow on the ground. Why would you bother with insulation when the coop is basically open?
