You feed the chicks Chick Starter, until they've outgrown that. Then you feed them All Purpose Poultry Crumbles while they're not laying eggs. Once they start laying eggs, you'll switch them to Layer Crumbles, which has some oyster shell stuff made in it. You can also give them some cracked corn in winter, when its cold (if it gets cold where you are) to give them extra energy to keep warm. You can also give them sunflower seeds, cheerios, canned corn, lettuce, apples, berries, oatmeal, yogurt, and bread (in moderation) as treats, and they'll love you!
