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...
I would say NOT wyandottes....I have had three at one time, only one left now because he's too handicapped to do anything. I also picked up three from someone to send to freezer camp because they were so mean.
