My husband and I are bumping heads here... He doesn't think I need a lot of ventilation in the coop. I sent him this link https://www.backyardchickens.com/a/...-go-out-there-and-cut-more-holes-in-your-coop to prove him wrong. I will have my vents! LOL As of now, I have a heavy sturdy metal shed, with solid walls (meaning no windows)- that is changing soon. I will be adding 2 windows, the "doggie" door that will lead to the run, and I want to put one vent at each peak (one in the front, one in the back). The walls are bare and we plan to frame it out and put walls up. Today, we bought thick sheets of styrofoam to put between the studs, and will put wall board over that. He said that is the best insulation. He does not think the fiberglass insulation will be good, bc the shed is old and has some small holes here and there. I am going to try and patch most of them, but it would be impossible to get them all. Overall, it is mostly dry, but he worries about the fluffy insulation getting wet and whatever. I see his point to a certain extent. So my question is... is it even worth putting styrofoam insulation in there? It only has an R value of 6. I feel like that is pretty much the same as having no insulation, because the heat will go out the vents. Any suggestions? The coop is about 8x12. I just don't want to waste money on the foam insulation if it is pointless with the ventilation. It was probably $80 just for that stuff! Oh, I live in northern IN and we get a lot of bad lake effect weather in the winter time from Lake Michigan. Thanks for any and all advice!
