Happens a lot (I think)....I have found one doe fawn in the middle of an open field dead gored by a buck. The moring I found it, I had hunted that field the night before and seen heavy rutting activity and bucks chasing off fawns. Weeks after that I had seen a doe fawn with her hair on her back shredded. Assuming from a buck breeding her because of the Horizontal marks. I think it happens in area's where the buck to doe ratio is about right. The rut is a little more intense due to supply and demand
