I can tell you EXACTLY what is wrong.
Four years ago, I had a six point come upon me. He looked thin, but it was the rut and I wanted a buck.
I shot him (bow), and though the shot wasnt that great, he ran only 20 yards then collapsed mid stride, and died.
I came up to him, turned him over, and almost puked.
He (as well as your doe) had been the victim of a poorly placed head shot. His whole lower face was black, with dead tissue, blood, bone, and his tongue hanging everywhere.
It was disgusting, and I butchered him anyway, and it was the nastiest meat I have ever had....
Your doe appears to have suffered the same plight....so maybe this is a note to people to stop with the headshots?!?[:@]
