Can corn snakes eat chicken

Yes, they can, but deer corn is whole kernel corn. It is much harder for the birew to digest in that form. It would be better to feed cracked corn, corn that has gone through at least one stage of a mill. Deer corn is usually fed to deer, cows and other large animals that will chew it to break it up. Chickens, of course, have no teeth, and if a chicken has a choice between whole kernel corn or cracked corn, it instinctively goes for the cracked corn.
