I have an OEG X Dutch bantam. She is mean, mean, mean! She fights with all other hens none stop. She has already had 3 batches of chicks and only lays when she feels like it. I have tried to introduce new hens for the poor roo, but she keeps them on the perch. if thier feet touch ground she's on them like hot butter! She chases them, kicks them and pulls out feathers. I put her in the coop with my bigger hens cochin x silkies and she even beats them up???? Can I change this behaviour or is she a gonner? Once when I took her chick away she actually crowed like a rooster????? HELP please!
