Raccons are notorious for this type of damage - looks like the same kind of mess one did in my daughter's yard when I house-sat. I was picking up trash for an hour all over the yard because there is no way it was a dog - Coyotes come around her property but can't and never have gotten in. However Coons are so nimble with their manipulative paws along with collapsing spines to squeeze through small places, climb rain gutters, climb block or stucco walls, etc. It's hard to imagine a 20-40 lb animal being so strong to do that kind of damage. I watched a documentary on the American Raccoon and they become more clever and nimble with each succeeding generation and teach their kits these clever new innovations. A Raccoon's litter can be from 4-6 kits and the dutiful mother forces the kits to learn her secrets of manipulation, opening locks, finding loose wires and boards to tear open a small entrance, squeeze between doors to enter barns, coops, and sheds, etc. In Ontario Canada a Raccoon broke through a front door to viciously attack a man in own his living room! Even in the city alleyways Raccoons will not give up their status and hog the space from stray cats and rodents. They are becoming more aggressive coming out during the daytime now. The American Raccoon has populated from Southern America to Alaska. In Japan the imported and now feral American Raccons have so overpopulated the forests as to begin damaging Japan's historical temples with feces and urine rotting the wood and collapsing structures - there's an active program established to eradicate Japan's Raccoon populations. Chicago and Ontario Canada have the most severe city Raccoon problems and only getting worse everywhere in the U.S. Your landscape lights were probably broken because Raccoons are curious creatures and love taking things apart. They don't always kill chickens for food either but love the frenzy of killing just for the chase!
