You could try the seperation method, see if it works.
Usually all my hormonal teenage cockerels, harrass the ladies, or gives the Alpha a hard time, & never target me. They usually get manners smacked into them by the older hens.
The ones that I get occasionally, that attack me, are Human aggressive, which are none curable. My Boy Demon, a Black Sumatra rooster, he's 1yr, & hates my guts. I've tried to fix him while young, but it's in his genetics. Gonna cull him this year, & replace him.
Can you post a picture of him?
Gamefowl are human friendly, those who attack their keeper are called Man Fighters, & are often culled from the bloodline. But I doubt he's a Game breed.
