Nah it never occurred to me...
If you read the article I believe someone mentioned a tag. Anyways, my point was solely on the private property issue. And when you start factoring in this guys livelihood is raising deer for antlers it kind of changes things as far as being considered a jackwad.
Yes it does mention a tag, forgot seeing that part or I'm illiterate, which is very possible.
So did the state say the hunters could keep the deer or did he make the decision on his own?

Seeing as it is his personal property he has the right to do as he wishes with the results of the deer escape. So he could probably force that he regains some or all of his property or allow the hunters to keep what they harvested in a legal intention, assuming they could not see an ear tag blatantly. Sounds to me that the owner is a stand up guy and apparently made the decision to allow the hunters to retain possession, call it a gift. In a case like this there is a Deer Hunting season involved with licenses alloted to individuals versus your analogies to cattle or bison. Last I checked there is not much for Bison hunting in North America and you still need to have a license to publicly harvest and to my knowledge there is no license for hunting cattle at all.
