yeah, Big M that has a LOT to do with it, but all my birds, save one, were all handled lots as babies. In brooder in my dining room. All of them got the same attention. But my BR's are still the friendliest. One I bought as grown hen (PR) and she does not like to be handled at all. The best I can do with her is pet her tail feathers just a bit while she's roosting. And I couldn't even do that when I first got her. She was not handled by her previous owner, all he did was collect eggs and feed his birds. His are not pampered or petted at all I guess. When I first got her, I called her "Osama Bin Layin", lol. She would go after the other chooks even when they were not in her space, had them terrorized! I kept sayin to them...there are 14 of you, and only ONE of her, gang up on her! But, she has slowly settled in with the flock, just not people friendly.
