So I have a flock of eight chickens in my suburban backyard. I have 2 Buff Orpington, 2 Easter Eggers, 2 Light Brahman, and 2 Black Australops. They all get along famously, no picking, no bullying, no fuss. However, I'm foreseeing trouble in this aviary Eden; I think one of the Buffs is a rooster. It's a lovely chicken, not a trouble maker at all, very sweet, and always first out of the coop, giving everyone else the courage to venture forth to eat the goodies. Its twin had a very small comb, but they are about the same size. They are about 10 weeks old, out of that awkward teenage phase, and into the sophomore in college stage. They are very well behaved, they study hard, attend their classes, and don't go to keg parties. I would love to keep it, but I can't have have roosters in town. I'd rather give him away than butcher him, it is a lovely chicken. Is there any way to know if he's a rooster or not before he starts crowing? If I know now, I can start trying to get a home lined up for him. No spurs yet, but definitely a comb and some wattles. What do you all think?
