Miss Lydia is absolutely correct. Take care of the hen FAST. I made the mistake of waiting a few days to see if they would get better and work it out. Then everyone ganged up on the poor hen on the bottom of the pecking order, including the other hens. She was a gonner by the time she was removed and put by herself. Don't wait! Put her in with the chickens if you have to. That is where mine went to be safe.Put the one who is being bullied with as couple of the more docile girls to give her a break from this drake. if you don't they may stress her too much and you lose her. Or put your drake in permanent timeout. you need to figure out something asap.
