Late this fall i got a few partly grown chicks from a casual local breeder. He keeps several kinds together, but mostly Silkies and Easter Eggers, but has been breeding for several generations, and there may be more in the mix. I don't know exactly how old they are. I'm concerned that the two big ones shown below could be roosters. I don't have prior experience with Silkies or roosters, and i'm not sure how to interpret the signs in a mixed breed. But these two seem to be growing a bit faster, and the feathers remind me of pictures of roosters. They aren't noticeably more aggressive or boisterous than the other chicks we got at the same time, and i haven't heard anything like crowing, expect one time, when she was really disturbed one made the "ba- bawk, ka BAW!" cry that i've heard some of the other hens use often after laying an egg. It's not clear from the picture, but one of these has the extra toe, and the other has heavily feathered feet. Thanks.
