This is chick # 1. She has four toes and feathered feet, and as I said before, is about a week old.
This is chick # 2. She also has four toes, but is clean legged, and I think that she is bearded and muffed, and of course is about a week old.
Top is likely a banatam Cochin. If it gets really yellow feet, that are feathered, and grows more mop like, it will be a Cochin.
I don't think it looks feathered enough on the legs to be a Booted Belgium D'Uccle, but if the legs are very heavily feathered, it may be that.
The bottom one may be a Blue D'Anver, but I'll let others with better expertise than myself have say on that.
