We can have 30 per acre as we are zoned agriculture. I have 1 Buff Brahma Roo, 15 Buff Brahma hens, 2 Buckeyes hens and 6 chicks that the mamas hatched and are raising. Two chicks are crosses and I can't wait to see how they end up. To this point it looks like they are red with feathered feet! Coop is a 8X16 barn with two safe runs. We also free range much of the time, even with the predator pressure - bald eagles, mink, fox, coyotes, raccoons, osprey, you name it we have something trying to eat our chooks.
