Oh Man! I just found this thread. Alycia -- hugs and more hugs to you..... I cannot believe what you are going through.
Please give your neice hugs from me and my condolences on her loss.
As far as your property/neighbor dispute, it sounds like you are doing everything the right way. I just cannot imagine the living H*LL you are going through. I think you are wise beyond all measure thinking far enough ahead to consider selling if you can get fair market value. You don't need that kind of stress and it sounds like this looney toons isn't going to quit.
I LOVE THE PIG FARM idea...... Would it be possible to move the chickens to that side AND STOCK UP ON ROOSTERS? Twenty or thirty might be enough

. They can sing him awake every morning about dawn.
hugs and more hugs, my young friend. Keep your chin up and above all KEEP THE FAITH. When one door closes another opens..... maybe you are supposed to be somewhere else.
