Yes, but in moderation. Do not feed them too much, that's comparable to only eating fast food daily and adding the pickle! Give them primarily pellets but give them a few kernels as a treat every so often. If you are planning on slaughtering them, however, corn is good to fatten them up, but feeding it to them if not, under those circumstances, can produce some really bad side effects. Egg production can decline, or have clear egg and other weird effects.Can i feed my chicken just whole corn. I free range them and I have a lot of land and a river. Is that enough?
Feed them pellets but give them a few kernels once every so often, it is very much a treat. It shouldn't be their full diet.
