Well, let me tell ya... my Rico suddenly flipped out not too long ago and started attacking me. He flogged my legs, came at me several times, and this was NEW behavior.
We figured out, it's summertime now & I'm outside in skirts and shorts a lot, and Rico is scared of my lilly-white flabby old lady legs. LOL! He never tries to mess with me when I'm wearing pants. One day in particular, he started pecking at some of the younger cockerels, as well, and was rough with one of them & hurt him to the point where we had to put the young cockerel down. It was really sad.
Anyway, we thought we were gonna have to get rid of Rico, but I did what a previous poster said... I picked him up, chilled him out, stuck him under my arm, and walked around with him being held. I have to do it once or twice a week, but he doesn't mess with me OR any of the other chickens anymore. He acted like he was gonna come after my legs this morning, but I reminded him it's no fun to be stuck under MY arm when he's trying do his morning chase-and-mate with his hens. It chills him out quickly, and he does not get hurt. He knows I'm the boss & now he's very contrite and submits to me in the yard. It'll be that way until I scare him with my white legs again. LOL!
