Yikes! Its awful that you and your dh have to live next to someone so nasty. We have neighbors on one side of us that are equally dumb but not half as mean. I suspect they feed our chickens scraps as well since every weekend when they bbq and have friends over our birds line up against the fence and start to yell out the way they do at our back kitchen door when they want food. I have also seen our birds running wild with little pieces of white bread (yuk) we don't even eat white bread, so if I was you I would let my landlord know about the issues with your jerky neighbor man. You can also file a report with the authorities just to let them know you feel threatened, that way if ever actually need back up its already on record that he was hostile/aggressive.
