Wow! That has to hurt... It's amazing how tough deer are though. We had a three legged doe on our hunting land in PA for 4 years before she either was killed by a hunter or died of other causes. Where I work I see a lot of deer with bad injuries from cars that survive and do OK. My Great Uncle Paul ran over a fawn with his combine one spring back in the 80's. The fawn got up and stumbled into the woods. He could see it has been hit bad, with one leg badly injured and what looked like blood coming from its head. No one saw the fawn again even after my Uncle Paul tried to find it. 3 years later, a guy on the adjacent farm shot a spike buck. It had a 4" spike on one side. It had no antler growth on the other side of its head and was missing its ear. It also was missing most of its back left leg. Pretty amazing a fairly young fawn like that could survive!
