I did pick up some banty cochin/silkie/frizzle cross roos from someone (they had too many), and they were easy to handle.
But yeah, the one SLW I have probably would be meaner if he didn't have curled toes, curved keel, and hunchback, and something funky with his neck, but he's the way he is, and can't do much about it. I keep him around because he can't do much, and he does like the girls (and they like him).
I had two RIR - one was a holy terror, and one I have now is aloof and avoids people. He is an excellent roo, gentle to his ladies, just a good flock manager roo.
