Any suggestions for a good cheap way to insulate a tin roof on a very small coop (3'x3'x30")? I am almost done building the frame! So far it has been totally free. I'm even re-using the screws that were already stuck in the scrap wood I am using, I haven't had to buy any more of them yet. I intend to use it to brood chicks in that are too young to be in the main coop, but too old and stinky and active to remain in the house brooder, or use it for broody hens to raise their babies in. I also may use it for a breeding pair or trio of silkies. I want to add a run later, but for now its just the coop part. I may put it on legs later on and put wire around the bottom of it to add another level. Anyway, I am trying to keep my expenses down, so I need some ideas for how to insulate the tin as cheaply as possible. Anyone?
