I had 3 hens that were aggressive. "Baby Gaga" was a silky EE bantam mix, I thought she was a rooster because she would always beat up my legs, and not even her brothers did that, But then she laid a green egg, I was so happy, I cuddled her, then she never beat me up but would come for cuddles, I think she wanted to be cuddled all along.
"Kato" a Spitzenhauben named after Kato from the pink panther movie, who would always attack the inspector when he would come home...."Kato,...not to night....Kato" Would still get beat up.
and a silver penciled rock hen I named "Assassin." Once she started to lay eggs she started to leave me alone.
