I believe my babies are about 4 months. Tractor supply couldn’t give me an estimate. I’ve had them since little chicks and they have grown super fast. I’m a little worried this ones a rooster. Her/his? Name is Oreo. So gender neutral but not aggressive like I’ve seen other roosters act but I also treat them like babies. The two black ones are about a week and a half behind my red and white one. Not necessarily in age but joining the family. So I was stunned when this ones waddle and comb was so big and red. Thanks in advance!
