It isnt a Cochin because it has 5 toes, and not a Silkie because it doesnt have blue skin, and I dought its a Faverolle because of the simple fact that the chick pictured has a small crest and Faverolles dont. Id second the Sultan comment.
Cabe, there just aren't many breeds with 5 toes, crests, and feathered legs. Unless it's a mixed breed, I'm going to go with Sultan also. They're medium sized birds, they will not be as big as the standard layer or duel purpose breeds. I have two of them (male and female), they have a gentle nature.
But leg color isnt what it will be when they get older. We had sultans that hatched out with pink legs and they ended up with the proper slate legs. Both silkies and sultans are supposed to have the same leg color as adults. The only for sure ways to tell the differece in chicks are the comb and when the feathers start to come in, one is ragged and one is normal.
