Help with pecking roo

[Gloria]

My BO roo is about 3 yrs old and for some reason he keeps pecking on one of my hens head. It just seems to be the one hen, she is a one yr old BO.

He chases her down and doesn't try to mate with her, just pecks her head bloody. This isn't normal right? I don't know what to do about it. Sometimes I let her out to free range by her self and other times I let all the hens out and leave him locked up in rooster jail (their pen) for the day.

This is my only rooster and I can promise you I will never have another one.

Any help out there?

She may be the dominate hen and he is putting her in check of who the top rooster is around there. I am not real sure of why he would do this but I'm sure someone else does I will be keeping an eye on this one.

Nope, she is next to the littlest one out there. So no dominance thing going on other then him.

No one has any other ideas?

It is an abnormal behavior which may get worse. I would be afraid that he will eventually kill her. I would either rehome him or her. When they start an unusual behavior like this, it rarely goes away.

I didn't think it was normal because he's never done it before. He also doesn't do it to any of the other hens either.

Thanks for all the help everyone. I appreciate it.
