Quick questions, I have 2 red sex links, 1 wyandotte, and 1 bantam cochin. Is a 4x4 foot COOP big enough for them as far as for inside? Their coop will be on stilts so they can go underneath to get more floor room during cruddy weather, but I just want to make sure it's not too big. I'm tight on money and don't want too big of a coop. If it's definitely big enough, maybe I'll just put their nest box (like use cat liter boxes) inside. If it's just enough room, I'll build their nest boxes on the outside like most people do. Thanks so much!
