So I got a new young chicken from my uncle. I was told it was a hen and never saw the chicken up close until I got it home. (It was in a crate.) It has greenish tail feathers, and is HUUUUGE compared to my others. I have a Delaware hen and three that I think are mixed with a kind called High Line Brown. I think this one is a RIR. The bird is not aggressive towards people, or overly aggressive towards the hens, although it did try to fight my one hen at first and pecks the others now and then. It crows, but it's not extremely loud, it has a large comb, but doesn't have spurs. If it's a rooster I have to get rid of it. I'm not allowed to keep them. Help!?
