It’s obviously thriving so it must be getting enough to eat. Does anyone know if this is a genetic trait or if it’s just a chance malformation? Should I worry about this trait turning up in my chicken population if she breeds? Should she go in the freezer when she gets old enough or will she be OK? My mother had a duck that had this same problem many years ago and she named him Einstein because she said he always came up with such cleaver ways of getting his fair share of the food. He never did breed….none of the female ducks would have anything to do with him so I don't know if it's genetic.
