What foods should not be given to chickens? I have some leftover cooked corn grits with butter & salt. Would that be okay? If the hens eat less of their feed and more scraps and greens will they lay less eggs? Which is better crumbles or pellets. My 4 chickens are 5 months old, they look full grown, I'm still giving them chick starter, they are not laying eggs yet. Any suggestions to the above?
