I am a semi new chicken owner and have never had a rooster in the past. I have two Buff Orpingtons and two Plymouth Barred Rocks. I believe one Buff is a rooster and one, maybe two Plymouths are roosters. One Plymouth is lighter in color and has a decent wattle and comb, while the other is darker and has a small, not so prominent wattle. It would be nice to get opinions.
