I'm new, this is my first post, so I hope I'm doing this in the correct manner. We have 25 mixed breed bantum hens and 2 roosters. Our hens are very skinny, you can feel their breast bone and they feel very light. We feed laying pellets (always available), table scraps, grasses and other fresh pulled green plants, cracked corn, oyster shells. They are not free ranging but have a large pen and henhouse. What can we feed that will put some weight on them?
