I had a similar problem this summer - 4th of July my neighbor had all of his family down for a huge party - they camped on his lawn which was cool, no problem there.
He sent his kids and his nephew over to buy some eggs for everyone one morning for breakfast, and the nephew was chasing my geese and spitting at them.
I called the neighbor and he took care of it, but the kid's excuse??? He is from NY City and has never seen farm animals
Um.. sorry, sweetie (he was about 10 years old) there is no excuse for chasing and spitting at any animal, much less a goose - dogs, cats, any animal you might find in NY City, you would not do that to, right???? Lame excuse, if ya ask me.
I told him that if he torments my geese they will get mean, and they will recognize small children as a threat, and next time he comes over they may attack him (or one of his cousins - who aren't much better, but they are afraid of me
so they behave over here).
Thankfully my neighbor is a good guy with more sense than your neighbors, so he told the kids they can't come over alone for eggs anymore.
I would perhaps explain to your neighbor that if the chickens get chased that they may become mean (or at least the roos) and you don't want Dear Little Satan to get harmed by your rooster if he takes the kid's actions the wrong way.
Maybe if they think the
kid is in danger they'll respond with some common sense.
