Purpose of this effort is to demonstrate first, your behavior can actually promote the man-fighting / human aggressiveness and secondly, you can adjust your behavior to promote a reduction and even stoppage of the behavior. I have lots of roosters so diversion of this one is not a major loss. He is the only one representing 20 of his kind that is even the least bit sassy. In the end my intent is to provide people with an alternative to the "crock pot training regimen mentality" where they re-evaluate their approach to more effectively prevent such problems from occurring in the first place. A genetic (nature) component is operating but the husbandry (nurture) part is also at play and can go a long ways towards preventing such problems from arising or over ride genetic force that otherwise works to prevent such aggression..
The best detail will be provided when others post their videos showing their interactions. We than then pick apart how the keeper promotes the aggression. You will soon see more than one way to make a monster and that mentality likely varies according to the method of making it.
