You Might need to separate her and gradually introduce her back in after a couple days if she isn’t separated already. This happened with my chicken and now my hen that was pecked on is perfectly fine with the rest but also does just depend on your hens. Every chicken is different. I hope this all works out! Is she loosing feathers?
That's what made me take her out, but I've tried to re introduce her about 5 times and I get the same result, I've even thought about getting rid of the other three hens because it's a different one starting the problem every time I try.
First make sure you have pleanty or room for your birds. Space, space and more space.
chickens that have lots of interesting stuff to peck and scratch through pick on each other less.
Also put "stuff" in the run so there are obsticles extra roost bars and vision breaks. Make it messy, so there escape routes and places offering safe zones.
Offer food and water from 2 or 3 different places so low birds are not kept away from those resources.
I would stop separating the low bird. It just makes her more of an outcast. She already has no self confidence and separation makes it worse. Try putting her with just the rooster and see how they act together, then add back the other hens one by one. Separating them may humble them some.
Remember that chickens are the closest living decendents of t-rex. Pecking is comunication and thats not going away.
Thats why commercial egg factories trim the beak off their hens or they would turn canibal.
Good luck!
Oh the rooster loves her, and they are fine with the fence between them, that's why I tried to see if she could go back in. Ill pull the hens out and put her with the rooster, I have a second coop almost done. Maybe if she gets to claim the space as hers it would change.
That would work out better because I want the rooster to breed her, not the mean 3, its kind of funny the 3 mean hens are like the three witches from hocus pocus,lol.
If the rooster loves her, then you can put him with her in her isolation for a little while (2 days probably) then when you reintroduce her to the flock she will have a stronger bond with one and he might protect her. I did this with 2 of my hens ,and might work for you . Worth a try.
She can see the others and they can see her through the fence and they don't react to each other at all, but when I put her in she runs around and I think they think its some kind of game of tag. Ill have to see if she can bond with the rooster if they are together alone because I've run out of ideas.
