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.
Why does this neighbor not have the right to kill a deer on his property? This is what's wrong with hunting now. Everyone thinks all the deer and turkey belong to them. Unless you have thousands of acres those deer cross property lines all day.
