When I got my chicks at 2 weeks old the lady told me that these two were different breeds. I believe she said one was a black sex link and the other I can't remember. At first they looked different but now they have the same type of coloring. Can you tell me if they are the same and what breed they are and also what kind of eggs they will lay? One girl has more brown flecking throughout her body, the other is mostly under her chin and some blue tones on her body. They are about 9-10 weeks now. Thanks!
