I ordered a batch of Buff Orpington chicks from Murray McMurray for the end of January. They threw in a "free rare chick" but didn't say the breed. The chick is now 7.5 weeks old and, from comb and wattle development, I believe it is a rooster. I first thought it was a silkie, but he isn't developing a puffed head and his feathers look normal. His skin also isn't black, his feet are feathered are yellow with black scaling. I also noticed that some of his back feathers have a green iridescence to them. He also is smaller than the buffs, but that isn't exactly unexpected. Here are some pics I took of him today. I can try to take better ones tomorrow. He was being rather wiggly. Here is a pic of him at 6 weeks.
