There's nothing to be done about this. I have called the FAA. I have seen, with my naked eye, 2 out of the three identifying numbers on the helicopter, and from my description, the (very nice) FAA person says it sounds like a police or Federal vehicle. It is not even as high as the tops of the trees, and my chickens are terrified. I tried calling the state police--I found the number of the aviation division, but there is no answer. (Perhaps they are all out in the helicopter). The chickens are terrified, and I am terrified and furious. They keep flying low in the valleys, and then popping over the house so that I can actually feel the wind on my face from the blades. It's outrageous. If the chickens were penned, they might have hurt themselves against the walls trying to get away--I'm afraid for the neighbor's horses, too. FAA Mike is trying the state police, too, but I haven't much hope, and now I have a migraine.
