BackYard Chickens - Learn How to Raise Chickens

How old are the chicks? Are you sure it’s not just establishing the pecking order? Do you have any other chickens besides that hen?

The chickens are 5 to 6 months old, I only have that one hen, I dont think shes establishing the pecking order she sees them and runs at them then flys up and claws there back and some time she does just peck there beak or there back but other times its a lot more aggressive but then they will run away and she goes back to doing whatever she was doing before she saw them, thanks for replying

Can you keep the old hen in the cage for a couple of days and let the other two just roam around in her old cage? Make sure she sees them.

I have done that but she gets mad and stressed I also let the new ones sleep in her cage and put her in the green house (that is where they have been spending the night) but she wasn't very happy with them at all so I let her stay in her cage and put the new ones in the other cage right next to hers where she can see them
