We live in eastern Canada so we have varying weather year round. Our summers are hot and humid and our winters are windy and cold. we see temperates in the summer in the 20s Celsius and can see -40 in the winter. I am building a new coop to accommodate our growing flock and I am wondering what is the best way to insulate it, or if I should insulate at all. I have large windows for both sides and there will be a door on either side as well. I will be putting in gable end vents as well as roof vents. I am a carpenter by trade and have a good understanding of how much ventilation they need and how to accommodate them in that sense but I have read a few different things on insulating the walls. Should I leave the walls uninsulated and insulated only the floor of the coop?
