Yes he did the right thing. Id be sick, if i found out i had killed a tame deer- but he couldnt have been sure when he shot it.
I cannot speak for him but if something like that started showing up on my camera pulls, I'd know it was anything but normal.
Still wouldnt change the fact I'd shoot it but I'd be highly suspicious of what I killed.
Down the rabbit hole…when this dude killed this deer, did it(the deer)act like a pet or did it act "wild". I know nothing of farmed deer behavior but I do know a thing or two about wild deer and their tendency to walk on glass, as most of us do.
Maybe the hunter was caught up in the moment but the more I think about it I have to wonder if this deer had no clue what was going on, was he just going to a bait pile like a calf to a feed trough?
