I ordered Americauna Hens, but I think I have a Rooster! He/She has NEVER crowed, I think they might be 5months or so, I can't remember. I raised them, and I had a busy summer. The hens haven't started laying and I think that maybe they are getting ready to lay and that's why he/she started crowing. I didn't think I had a rooster because it's so friendly and it never crowed! It's twice as big as my hens, is the only white chicken, has a green shimmer on the tail feathers and the comb is RED! It's very vocal now!! My Americaunas follow me, the are not aggressive, and come when called. I handled them a lot as chicks. They are sort of flighty but when they notice it's me, they all come running. If this is a rooster will it become aggressive? Do I have to separate it? How do I keep him quiet? Checking out the ladies! Wasn't happy being separated.... Giving me the cold wing!
