We have seven 13 week old chickens from MPC. They were all supposed to be girls, but one is definetely a roo. He is friendly, but the large comb and wattles, and the tail feathers, and the little stubby spurs coming in all say roo. I live in a neighborhood- on a 1/4 acre. No roos allowed. No crowing so far... trying to rehome him... trying to get an idea of how much time I might have. He is a GLW if that makes any difference.
