How old is the Chicken. Is he young under a year(Cockerel), or one year, & over?(Rooster)
If he's still young, it may still be possible to teach him manners. Method I use is the FootBall method.
I pick them up like a football if they kick me up my legs. I hold them nice, & tight, but not squeezing for about a minute.
My main way of taming is from day 1, & beyond. I hold them, & wear the color red(Optional). There's only 3 butt heads in my flock. 1 bantam silkie that likes biting me, a Porcelain D'uccle who likes to bite me occasionally, one time he actually attacked my face(Years ago), & a Black Sumatra named Demon. He kicks me up my legs occasionally, & when he does, I use that method I mentioned above. It's been a good 3½ weeks since he did it last.
If I can't tame them, we eat them. No highly aggressive roosters allowed.
