I am researching barns. This barn will eventually house chickens (my breeding pens) on one side. The other side will be for goats and sheep. One small space will be for tools and whatnot. I keep thinking of doing wood because of the insulating properties. Winters here get down occasionally into the teens, but not tons lower. Summers are wretchedly hot. It routinely is in the mid to high 90s with a zillion percent humidity. I think metal would be too hot in summer and would toast the chickens. My dad keeps touting the metal barns due to their durability and the fact that they don't have to be repainted all the time. What experience do y'all have with barns and which do you prefer?
