I have two Blue Americaunas. I can not figure out if they are hens or roosters. They don't have long tail feathers. They are 17 weeks old. One started crowing about 3 weeks ago and the other one started up about 2 weeks ago. I have no roosters and I live in the city so I can't keep them if they keep crowing! A neighbor has already threatened to call the city if I don't "abate" them by Labor Day! They are beautiful birds.
