Can someone help me by telling me what kind of chickens these are? I don't know how to post pix of them so am including my facebook album link. http://www.facebook.com/media/set/?set=a.2070631646966.2100178.1280109042&type=1&l=aed0504061 The black one has huge feet and is terribly mean even as little as he is. The other two are pretty friendly. How can I tell if they are hens or roosters?
