Neighbors yard

Not that I know of ... but a fence would work

How big is your yard?

 

Welcome! Your birds, your problem! Either keep your birds in a fenced run, or fence your property somehow to keep them at home. Electric poultry netting works to make a movable run space for them ,and protects them from ground predators too.
Be glad that the neighbor hasn't solved the problem permanently already!
We all need to keep all our animals at home, or there will be consequences, not so nice for the trespassing animals.

Fencing will be a good start, but they already go over there so it will take some training as well. And maybe a clipped wing here or there,,,

 

I used a battery powered driveway alarm a few years ago to train my guineas not to go to the development behind me. It is not a deterrent & you have to be there to scoot them back when they cross the line. Eventually they learned not to go that way. I placed it at least 30 feet from the line so I had time to get out there. Won't do any good if you are not there.

 

With this setting the burden is decidedly on you. You are responsible for all containment that will likely also be the predator control. I suggest you fence birds onto your property and clip wings to deny them the ability of flying over it.

 

People think free ranging is the only way to raise healthy hens, I disagree 100%, I have a large moveable tractor that allows them fresh grass everyday, a nice view and they are safe from predators and neighbors , this option is cheaper then a fence and really just a box made of hardware cloth. Mine is tall because the man made it, but my smaller one is 3 feet tall and 5x5 feet

 

Clipping wings worked well for us.
We only have 4’ chain link on most of our back yard and some 6’ wood fence too.
They were hopping over the 4’ so we clipped one wing on each bird (throws them off balance) and they’ve never gone over the fence since.
You may have to do it again after they molt though.
But a lot of times they just think they can’t jump anymore lol.
