I get that most people try to get most bang for their buck, tailoring their coop size to get maximum use of their wood. I'd love to have an 8x8, but my husband does not support this and I don't blame.... We're really just sneaking our playhouse-designed coop into out backyard (as cuuuute as possible). My other option would be to have a 4x4, but for my (planned) 5 banties, that seems really tight (there will be a sizable run attached). I actually am hoping to bump it up to a 5x5.... But it surely isn't using my materials to the best of their ability. My only consolation is that we're incorporating free materials (found 1/2 of dutch door with windows that will be used on one side of the coop), and we're using up the extra plywood on the external nestbox and decorative attached planters. I know my 5x5 will wreak havoc on my attached run in terms of hardware cloth.... Either it's too small or too big.... Anyone else with the inefficient sized coop?
