@WallyBirdie What other breed's do you have there that it could be mixed with? I have a hen that has 5 toes on one foot but 4 toes on the other. She is the mother of the bigger NN chick that @Parront has. That chick hatched out with 4 toes on each foot, while the hen's other chick that I kept here has 5 toes on each foot. Your chick that has the feathered leg's could be a throw-back to past breeding history of the parent's.
