I'm not a big fan of the mink family as one ripped my chickens apart for funsies, but the owner was likely a godawful person too. That many minks on a farm would have kept them in tiny cages. When you cage minks like that then go crazy, spend their lives spinning in circles and bashing their heads on the sides of the cages. Then they just leave them with open head wounds since taking care of them would cut from profits. We had one not far from us and an employee snuck out videos. So horrible. The animal welfare people knew what was happening and barely took action, I wouldn't be surprised if someone got desperate and thought they were helping. Without actually thinking it through.
