I don't think I'd be able to really identify that it is 100% a doe. The hind quarters were eaten completely off of all 3. When I first saw it, I seriously thought poacher because it did look like you said with the rack cut off but if it were a poacher, why not take the meat too? Why slaughter 3 deer and leave them lay? I showed the video to my BIL and his wife, they both said a pack of coyotes.
I honestly have no clue though between wild dogs or coyotes. I know we have coyotes down here... I'll cautiously go back and check it out in the morning but SIL figured it was a doe because of the two fawns very close by. She said she wouldn't have left them.
Your thoughts are more than welcome because I considered, when I found them, that I may have to call the game commission on a poacher. I'm just unsure of what to make out of it to be honest.
I also found the one fawns legs about 3 ft from the babies.
Really, one of the weirdest experiences I've ever had.
