So I have a rooster,hen,and 5 baby chicks. When we first got chicks (our hen is one of them)we had two barred rock chicks. Rocky, our rooster, always picked on them.When one of them died, Rocky started taking care of Little-bit more (our hen)but we still had to separate them because he pulled feathers off her. When she got older and layed some eggs he backed off. She went broody and we got 7 baby chicks (2 are gone somehow) the chicks are about 2 months old and Little-bit is treating them like our rooster did her. She doesn't take care of them any more and doesn't keep them warm. She now chases them when they get close to her and pecks them. She became distant after the other chicks went missing and they are all getting to higher ground. They are all free ranged. Pls help me!
