The process which removes the feathers- scalding- typically removes the tough yellow skin, so you should get nice pink feet, which do not need to be peeled. If, by some chance, your chicken feet do come with the yellow outer skin, you can clean them and leave them on (soak in a water-vinegar mix for 5-10 minutes before rinsing) OR remove them by briefly boiling them for a few seconds, then dump in a cold bath (The skin peels right off after. Don't boil for too long or the skin will stick!)
