I have a hen that is getting bullied out of feeding and I don't know what to do. I have 5 hens and a rooster...I'll call the bullied girl Cinderella. The rooster is John Wayne. Every morning I give them all warm oatmeal and John will keep Cinderella in the coop and out of the pen so she can't get any. Even if I try to feed her separately she won't eat because they keep an eye on her. She gets to eat enough of chicken feed that she's not starving, but she is smaller than the others and I don't think she's laying like she should because of it too. My coop is limited in size and I can't free range due to predators. Any ideas how to prevent this?
