Yea Deer lay down (,correct me if I am wrong) much like livestock
when giving birth,I walked up on an ole Doe this spring licking one and having another while lying Down,
I agree with Ruger ..one of those crazy shots you get now and then,either that or a Mack truck hit her in the ass.
The more I look the more it looks like something bad has happened to her....someone chime in if you can see anything,I see her joint showing at the right hock when I enlarged it.
tried to get a better look but the pic just fell apart when I enlarge it ...not enough pixels.
