Hi, I have 4 white silkies that were all supposed to be hens. 2 look bigger and have bigger combs and have wattles. I already have 3 black roos that I need to rehome. I also now have 2 polish roos! Too many roos and not enough hens!!!! Can someone help me out and tell me if you think these are roos too? I will try to get better pics posted, neither one are crowing.
