I would not shoot it and then leave it.
Looks like a black cheek patch. If so would be an illegal shoot.
If it was clearly injured I probably would not shoot because chances are that no meat could be recovered.
Certainly would not shoot a buck on a doe/fawn tag regardless of any other circumstances.
I am unaware of any mercy kill provisions in regs.
Did you punch your tag?
1. No one left it. It is currently being processed.
2. Wyoming defines "Fawn" as "a young-of-the-year antelope or young-of-the-year deer". "Buck antelope" is defined as a "male antelope with visible horns and dark cheek patch at the base of the ear". There was no patch at the base of the ear, just a thin line lower down. This one was a fawn by Wyoming's definition and I had a doe/fawn tag. It was a legal shot.
3. Yes, I punched my tag. And still had one left I never used.
