Hello, I've heard many things about giving chickens corn in the winter. I've heard that it helps keep chickens warmer in the winter and a few other things. I've also heard that you SHOULDNT give chickens whole corn because they can't digest it properly. But I also heard you SHOULD give chickens whole corn because whole corn has all the nutrients in it they need in the winter. Should I give them some corn this winter? If so how much and what kind(whole or Cracked) ?
