I've built a fantastic coop, but smaller than I would have liked due to cost considerations. It is 6'x6'x6' high, 18" off the ground and insulated. I've borrowed an incubator and plan my first hatching effort this Spring. I'm aiming towards 6 hens and 1 rooster, but already know that will be far too few to satisfy my growing addiction. Would there be any problems if instead I were to aim for say 4 bantam hens, 1 bantam rooster, and 5 standard hens? It gets pretty cold here in the winter so they will spend a lot of time inside despite the attached 12' x 16' run.
