He should make it, these animals are survivors!! In the early 90's we had a doe come on to the farm we were hunting in Orange county NY, with a hind leg dangling. We tried to dog that doe and put her down, and couldn't do it, she always stayed ahead of us. I read where a deer biologist claimed that a broken hind leg is always fatal to a deer. Well, thats just NOT so. The following spring, we saw her on the farm, leg chewed off cleanly, and she had healthy twin fawns.
