Not sure if what i'm about to share is correct but its worth starting some conversation in the thread. Someone once told me that if a buck has a messed up antler on one side like that, that it usually has suffered some kind of injury in the past. I found this to be interesting because i harvested a buck like this about 12 years ago. It was a perfect 4 point w/ eye gaurds on one side, and had a deformed antler on the other. He also had a very badly injured front shoulder that was healed over. He walked with a limp and the muscle tissue was all diminished on that side. I guess what i'm saying is that it may not be a genetics issue. I have never really researched this or had any conclusive proof, but it seems possible. It would be interesting to hear if others have harvested deer with deformed antlers on one side that have also sustained an injury previously. Also, with the tall fence in the background of the pictures, its not unlikely that this deer could have hurt himself sometime in the past.
