I bought 3 chicks from a local breeder and were told they were the rare silver sussex chicks. I saw his flock and he had what appeared to be silver sussex and light sussex hens in with silver roosters. What I got were 2 black chicks with black legs and a yellow and black chick. He said that he thought the yellow and black chick would be a male based on coloring. The 2 toned chick is larger than the others and is feathering out slower. I am confused about what I have because based on what I have been reading on BYC about the breed all sussex are supposed to have white legs. Also haven't read that you should be able to sex chicks based on color as they should all be black as chicks. Any ideas?
