Hen reintroduction?

[BabFarm]

I have four hens, two of which are Golden Comets that are about 1.5 years old, the other two are NH Red that are a year old. A few months ago one of the Golden's was being picked on to the point that she was bleeding near the ears. I separated her from the others so that she could heal. I then tried to reintroduce her to the other three while everyone was free ranging. The NH Reds immediately went after her and attacked her. Is it possible to have everyone get along again? I have noticed that the Golden who has been attacked hasn't laid any eggs so I wonder if she has a health problem. Looking for advice on options as I don't feel her temporary housing in a dog crate is ideal.

Thanks in advance!

Usually there is only one instigator in the bunch and then the other join in. You need to single out this particular aggressive bird and give it a "time out". I know that the giant dog crate is "not ideal", but if you are trying to restore harmony, that is about the only way to do it. This bully bird needs to be separated for 2 full weeks so that she not only comes down a few notches, but the rest of the flock can reorganize the pecking order. By the time the aggressor is released, she becomes the new bird and usually the fighting will stop. Sometimes the only way is the re home the aggressive bird. Good luck!
