Dale, you crack me up!
If I could catch a chicken...
I will tell you that I had toyed with the idea of spreading some rat-poison laced ugali in my sukuma plants. My fear was that my dogs would get into it before the neighbors chickens.
Keep in mind that my poultry also free ranges onto their side of the boundary as well. The only difference is that they aren't growing anything that chickens like to eat, and they had already harvested their maize before i turned the turkeys loose. When they planted their beans, they complained about my poultry ruining their beans. I told them I will confine mine if you confine yours. They did, so I penned up all my poultry and spent money on commercial feeds. But as soon as their beans finished flowering, they turned theirs loose again. 😛 hmmm, wait till they see what a turkey can do. No, that's my evil alter ego thinking aloud. I hope we will have chainlink around our compound before the next planting season, so my poultry will not harass them. I would rather model respectful and ethical behavior than lower myself to their level.
They aren't likely to leave, as this is ancestral land passed down for countless generations. And the kids from this family have been a hassle to other neighbors. They get caught stealing and handed over to their parents, who do nothing. (There are Like 10 or 12 kids there, I can't even keep track of them all.)
We just happen to be the closest, easiest target. (The grandmother will even cover for them. They cut a tree on the boundary line (not allowed) and it fell on my cassavas. When my husband called for the boy who cut the tree, the grandmother came instead and said she cut the tree! I'm trying to picture granny hacking through a 10 inch trunk with a machete?! )
We have discussed hiring a night watchman - a masaii. I think I even mentioned it awhile back in this thread. If you hire one masaii here, they tend to bring their friends, so you get 3 or 4 guards for the price of one. The husband and I decided at present that we don't really have enough assets to warrant a watchman, and would rather put that money towards much needed infrastructure. But if and when we finish those projects, and we have more animals, a watchman will probably be in order...hopefully the watchman doesn't also steal!
