My manfighter, Fallow, killed one cockerel and seriously injured another young chick that wandered into his pen. He is an all around mean cock and doesn't tolerate anything except his one favorite hen. I had another hen with them but he treated her badly and she went broody just to get away from him I think.
All my other roosters have no issue with hens or chicks.
