"Well I called the local sheriff department and talked to the nicest man. I told him what had happened so far and that I wasn't ready to file a report that would get him talked to by a deputy...yet. He was very nice and took down my info and told me to keep a record of any interaction (like you guys all told me to) and to let them know if it escalates.
Today I mowed grass and he was out in his yard.... He stared and glared. All I did was wave and smile. Go me. I wear head phones a lot when outside, so even if he had said anything I wouldn't have heard it.
I will be putting hot-wire around my garden anyway to keep deer and chickens out. So he would get a shock if he tried anything. I also have a game cam that I am going to set up, so if he sets foot on my property I will know.
And yes I am young and have worked my tail off to get where I am. I shouldn't have to explain that I worked 2 jobs 18 hours a day for years to save money and be able to do what I do. I am driven, I should not have to explain it."
Talking to the police and ignoring him (ear phones!) are your best bets. If you have any future problems I suggest you not confront him yourself and communicate through the police. Some of the more aggressive suggestions posted here may be fun to think about but will likely just escalate the situation and, I suspect, do not fit you. I do have to admit that the DJ with the 8000 watt PA playing AKs gets my vote for best creative reply!
I think giving him eggs - or anything from your garden - would be a big mistake. For one thing, it is rewarding bad behavior. For another, it involves you unnecessarily interacting further with him. You sound like a very nice and kind person, someone I'd like to know. There are plenty of people in this world that will appreciate your kindness. And plenty that will respect the work you have done to get where you are. This guy is simply not one of those people. Ignore him. Keep your animals on your side of the fence as best as you can and call the cops if he acts out again.
A visit from the police will likely shut him up once and for all so please don't be shy about calling them. Threatening your animals is more than enough harassment to justify a call; I'm glad you already talked to them. A lot of people like this will push buttons as long as they can get away with it.
PS I'm "only" on 1 acre of Ag zoned land in S. Fl. All of us out here are here because of the additional freedom we have. One neighbor actually wants me to get a rooster.
