Hello! My name is Eric I'm 17 yo and I want to start raising chickens for eggs in a house we just move into. I dont have any problems with the contraction part, i'm pretty handy, if I may say... I plan on fensing 16X16 feet for a run for about 5-7 chickens. I just have a question... Do I really need a coop? I live in a please that the minimum temperature at night get to no less then 50 F. Cant I just build nest boxs and roosts? They will be under a roof that i will build. possible?
