Other than injuries, it's just genetics. I killed a buck years ago that had a third, SEPARATE main beam grwing out between the right pedicel and right eye. It grew downward about 11 inches and still had a piece of velvet dried up and attached to it. The way it grew, I figured out, everytime the buck would lower his head to rub, the end of the third beam would actually go away from the bush or tree. So what caused that?? Who knows. I just thank the Lord for it and go on. I'ts beyond me, all the answers that is...
