Stop in for a cup of coffee

so I'm turning the wive's duck pen into Fort Knox. Its already a big pen with number 9 wire cattle and hog fencing, 1 inch squares. But something keeps attacking the pen trying to get in since we put them in Monday night after the free ranging ducks were attacked. Tried 3 times last night but runs off by the time i get out there. the current fence is 72 inches tall. I'm adding another 2 feet to it, putting a a pair of electrically charged barbed wire strands across it. hooking up a 300 mile, 15 joule fence charger to it(for only a whopping 450 feet worth of wire) adding night time security cameras. Whatever is attacking them is gonna feel it tonight. even worse if i get them in the shotgun sights.
