Well, I know that you can shoot a bear in the act of destroying livestock and poultry, and bear are the most protected in Pa, so I'm guessing nobody would cry over coons doing the same. Call the game warden up and ask. Our's here is pretty cool. They make their living on wild animals, but are also there to help farmers. He (or she) should be able to give you a bunch of tips on how to keep coons away. When the bear was here, mine told me ways of keeping bears awa, plus told me "while I would rather it stayed alive, the law fully protects your right to shoot the bear if it crosses the line, even if it just walks on your porch. But, if you don't want to shoot it or have enough safety, call me and I'll be down. To get it.".
So, game commision can be a very valuable resource.
