Hello, I have 11 full-size chickens, and no time to build a coop. I have pondered buying a storage building to make into a coop, but I was wondering if something pre-fab could be large enough. They will have a large pen to almost free-range in, so I'm not TOO worried about the space. I found this: https://www.hayneedle.com/product/littlecottagecolonialgable6x8ft.cfm Would something like this be okay for them? Also, I live in central VA. Would I need to insulate something like this? Thanks!
