Why is my rooster bullying this new hen?

[ohnoicantfly]

I added a new hen to my flock yesterday. I know you're not supposed to add only one, but it was add one, or lose the chicken. Most of the hens are okay with her being around, from what I've seen. Some chase her, but I believe that will subside in a week or two. My rooster is the problem. He chases her around and she's terrified of him. I actually used to own this hen, but we gave her away. Now we have her back, but it's been long enough that no one remembers her and her status is obviously gone.

She doesn't even want to go in coop with him in there. I had to put him outside to get her to go in. Should I discipline the roo? Or is his behavior normal?

Please help. Thanks!

Did you give them any see-don't-touch time?

How old is this rooster?

He's probably trying to get her to submit to mating -- accepting his dominance and role in the flock.

No, I did not. It didn't really occur to me, but even if it had, I wouldn't have had time to set any sort of partition in the coop, as she was given to me too soon.

The rooster is one year old. I've had him since he was three weeks old.

You didn't quarantine the hen at all? I hope for your sake she's healthy.
Take her out and give them time on either side of fence.

Do you have a dog crate to put her in?

For her safety so she doesn't get beaten up.

I can set up a little fenced off area in the coop where she would have access to a small run (my chickens are free rangers). I did that during integration for some chicks last summer.
