I brought home 3 chicks from the local school which I were told could be any number of different breeds. Two I have appear to be the same with black with brown edged wings, combs are dark colored. They have white down the front of their chests and down their tummies. They are developing really pretty reddish brown stripey feathers here and there. They have nice tails sticking out that don't really show in the pics. The white one has a comb developed that is a bit pink. He is larger than the dark ones and has a very short tail. I refer to him as HE but would love if he was a SHE so I could keep him. Any ideas what I have? These are my first chickens, so I could REALLY use your help. Thanks!
