I incubated and got 7 new chicks. I made a brooder section in the coop for when they were 5 weeks old, and they stayed there for 3 weeks so my original flock could see them. Afterward, I created a run section for them during the day, a couple of weeks later, slowly opening both ends for them to explore and mingle with the flock.
Everything went well, except for some hens. They don’t accept the new chicks and are mean and aggressive towards them. I witnessed one hen grabbing a chick by the beak and swinging it around. I isolated the bully hen in a cage for a couple of weeks, although she improved slightly, she continued attacking the chicks. Other hens also displayed aggressive behavior, so I isolated them too. However, their behavior hasn't changed despite the isolation.
Is there anything else I can do to correct their behavior, or should I consider rehoming them? These mean hens are 10 months old and good layers.
