In most cases, an injury happens to A buck that causes the antlers on the opposite side to deform. Its the deers body attempting to repair itself so it pulls protein from the other side of the body, thus deforming the uninjured side of the deers horn. Ive also found that once a deer has the deformity in the antlers from the injury, not only does that deer never regain a balanced rack, it also becomes a genetic trait that can be passed on to fawns the buck sires . Im in the same situation here . Just found out today that the buck i believe to have had the original injury was harvested by a hunter across the street from me. I have at least 2 more, younger deer showing identical traits, ie a normal 4 pt side ( the STANDARD whitetail 4x4 set ) and a fork on the other side . Luckily, i have pics of nice even 4x4 bucks too. Bad part is none of these animals are of interest to me. One buck i have named " donkey " is the only deer on the place im interested in taking. He is nothing special rack wise. Just an old saggy skinned warrior that looks to be in his last season . Got a pic of him at 4:44 this morning. Seems to come thru about once a week.
