I believe that a bad behavior in a chicken that seems to stem from breed and genetics is much more difficult to train out of a chicken, and most people sense this so they usually cull instead of spend an inordinately amount of time and effort trying to discipline and train. When the choice is made to train instead of to cull, you need to be committed to it and accept it will take a lot of time and effort.
This rooster would deliver such deep and serious wounds that most people would not be inclined to keep such a bird. Why I kept him and persevered, I really can't explain. Just an intuitive sense that he was a good rooster with a neurotic issue, which I did become aware of. Discovering he was reacting to my own bad behavior was a revelation not easily arrived at by most chicken keepers.
Chickens tell us important things with their behavior, and if we listen with an open mind, they can become the solution to the problem.
