It's my opinion that he will never be "right" again. If the injury was enough to cause the deformation this year, when he'd been injured
last year and has since grown new antlers, it will, I believe, remain for the rest of his life. I caught a buck with bad genetics chasing does last season. I decided to do the "right"(?) thing and took him out. He was at least 3.5, perhaps even 4.5 and a big bodied deer. It kinda stung to take him as my only Kentucky buck of the season.
Now, with your buck, I would also still believe that his genes are still the same and he will pass on whatever
he had at birth. I do not believe his offspring will have bad racks, because of his deformity now, if that matters.
