MILLET, my chickens went crazy over it!! But you have to watch them and make sure they dont eat too much. I had a baby get so fat she couldnt even walk. The hard boiled egg is wonderful for them to have as well. When they got older, and i never did this till i had peacocks, would take flies and pull the wings off and give them to the babies. They loved to chase the flies around. Then they discovered cat food and it became their favorite food!!
