I wouldnt like those people much. Not cool.Missouri has legislature to clamp down on the puppy mills. We talked to a friend who has a daughter who works for the task force that keeps an eye on the dog breeders. Unfortunately we were told that they are only clamping down on the big time indiscriminate breeders and puppy farms.
Meantime, the Amish breed and breed and breed more puppies and then don't take care of them.
Nothing more than another form of livestock to them.

Did that happen any particular time of year? I know a guy that had pheasants and had the same issue (with netting, I think), but I believe it was hawks. I could be mistaken. I've had owl problems, but it was with the ducks and that pen had no cover but the trees. That was my own fault.
