OK, folks, here's the scenario. I have a great coop on the 2nd floor of my barn (see video in signature line). It looks like I might be relocating out of state for a job, leaving my elderly dad with the chickens. I don't want him to have to climb up the rickety and steep stairs of the barn to the coop. I have lots to do before I leave, and building a new chicken coop from scratch is ideally not on the list. Any suggestions for an insulated pre-fab coop at reasonable price? I have 4 heavy breed chickens. They will have access to a covered run such that I am really looking for this coop to be a roosting and nest area. It could be smaller than 4 sq ft per bird. Or, tips for building an insulated coop from scratch QUICKLY? Thanks!!
