I have a chicken coop that is 8-feet, by 16-feet, and is 7-high, with 12 nesting boxes, could build more if needed. Question: Whats the maximum amount of chickens can I start out with, for this size coop? I want to find some Buff Orpington chickens, and a rooster? I live in Palestine, TX., 45-miles south of Tyler. My son and wife built the coup when they were temporarily living out here in my man cave in our paradise. They finally bought a home, and took there chickens. Am looking now for a seller/breeder?
