Help! I think my hens are killing our new rooster

....or hen!

...or henZ.

Here comes another option:

As the age difference is still an issue at this young age and RIR hens are known to be quite brutal, you could separate the little guy with one of the more docile hens in a see but don't touch area right along the others for 7-10 days. Then add another hen and so on until he is acquainted with 5-6 hens and they get along well.

Then remove the partition and let them mingle all together.

I did something similar this summer when I had an orphaned 2-week old chick. I separated her with a 5-week old (watching to be sure the older one behaved). They were together for about 3 weeks before I integrated them in with the rest of the flock. They are still bonded.
