Just saying 2 acres would be fairly easy to high fence, problem solved. I have a similar 5 ac problem but my neighbor seems to be a good guy and is not blasting them off his porch. If I had even a hint he was I would do it in a heartbeat. And if I had to spend the money and time I would make sure the part next to his house, which is about 5-10 feet off the line, was about 10 feet of the ugliest chicken house tin I could find topped by concertina wire and maybe a few spotlights. Just so he would get the message that 5 acres ain’t a hunting property.
