Football has ended and baseball hasn't started, deer season has ended and turkey season hasn't opened, so I am admittedly a little crazy, but I'm going out on a limb and saying that she was shaved by someone's arrow. I had a doe jump string several season's back and it left a perfectly shaved area right across her shoulder and back. If someone was in a ground blind and took a straight on shot while her head was down, you could get this effect. Far-fetched, and probably a fence, but just seems too clean a cut (more like a shave)for it to be barbed wire. Would expect hide to be damaged as well as hair missing from a fence wound. Hurry up turkey season...I am way over-thinking this.
