I had the same thing last week. Grilled them up and man they were horrible. Threw em. Im sure it was off my buck. I got a doe on the same hunt. The buck I had to come back the next more cause he jumped a fence and I couldn't next ahold of the neighbor. The temp wasn't a problem it got down to 8 that night. He bleed alot. The meat had a pink tone to it. Like there wasn't any blood left in it. My doe's meat was nice and red. Think I'll eat the doe first.
