The food portions as you describe is accurate, just not a detail I thought would effect the outcome. Some like their birds at a particular weight so I think they would feed accordingly.That is similar to approach I learned. It differed in that you approached the penned stag many times each time proving only a small morsel of food each time. Worked great for calming a flighty stag but some of havoc's issue might be man-fighter related and that is more of a need to stop doing something to prevent it from starting in the first place.
