I have a RIR roo who is an absolute doll. He can be a tiny bit rough on his favorite hens, but has never ever tried to go after me or anyone else. Very respectful. By the same token I also have a silkie roo and a red cochin bantam roo. The silkie tries to flog me every chance he gets. The red cochin pecked me the other day when I shooed away one of his hens, but otherwise is a little sweetie. He loves to be held. I also have two mille fleur roos. Both are respectful and don't go after me, and allow themselves to be held (after I manage to catch them that is).
So, when I raised up my babies I tried to listen to as much on this site as possible and not coddle the roos as they are there for a job. I try to keep a bit of distance between me and them, but handle them enough so I can deal with problems/injuries/issues.
I think as mentioned, it probably is more individual roos than breed. At least it is with my four boys.
