I have got a broody with 3 chicks (4 days old) in the coop together with the flock. The mother hen is my highest ranking hen in the pecking order and she does an excellent job at keeping the other hens away from her baby chicks. But today I saw the rooster go after the chicks and peck them repeatedly, especially one of them. It ran away from him squeaking but he went after it. The mother hen didn't intervene. The chicks by the way are the same rooster's offspring. How dangerous for the chicks is this? I wanted to raise them with the flock and I also don't really have alternative housing for them. Do I have to separate either the mother with her chicks or the rooster to prevent murder or is this normal behavior?
