i have 1 hen that i know is molting. ive been reading about feeding extra protien to help with the molt. so what are some favorites to feed for extra protien and how often should i feed them. should they have something extra 24/7 or just as a treat. they are on layer crumbles,oyster shell,they free range about everyday and i give them some leftovers everyday. so far it is just the 1 out of 6 that i can tell is molting,but i assume the rest will follow so i want to be prepared.
