sounds like there's tons of room for improvement if some company can just show up and kill animals without any verification, which is both great news and horrifying that the people involved could be so thoughtless
It happens here all the time (Killing animals on unattended properties, Australia)
Sometimes the owner doesn't even LIVE on the property where the animals are, and the butcher comes down with "third gate on the right, the one with the two trees, we want the two pigs next the the barn done" written on a post-it note.
Personally we've NEVER allowed any animals killed on the property without us being there but it's not unusual.
