Once I clipped their wings and they got to laying age, it really wasn't a problem anymore. I let them free range when I am home, but I don't stay out there with them. I doubt there is much to attract them to flying over to the street. Mine usually flew over to the neighbors yard, I think when they saw lizards or bugs over there. Plus when they did go over, they rarely ever wandered further than a few feet from the fence. Only once did they fly into the alley behind my house and go on an adventure into the other neighbors yard where I couldn't see them. I think they decided it was scary and never did it again. They also used to freak out when they decided they wanted back into the yard and frantically stick their necks through the holes in the chain link, as though suddenly they would be able to shrink down small enough to fit through a three inch hole. They never did figure out that they could fly BACK over the fence into their own yard....... sigh.
