I have six chickens. I live in the Atlanta area. They are of diverse breeds and i feed them mostly a diverse feed of non-gmo feed and cracked corn in the winter. They used to lay consistently, about two dozen eggs a week. (six chickens) In the beginning of December they stopped laying completely. And now they are molting. They are losing feathers and in the cold when they should be adding feathers. What is the problem? Thanks, Chris - first time post and patron to BYC.
