I killed a buck on Sunday that was 2-1/2 yo.

Both main beams broke and had very little antlers left.

He had scars all over his body from cuts to holes and tears in his ears from fighting. His bottom jaw was broke and just hanging

for my question is it normal for a 2-1/2 YO to be so aggressive. His instinct to fight and show aggression was so that right before I killed him he was rubbing a cedar.
