I had a similar issue with my gals, they kept jumping over to the neighbors, then freaking out because they couldn't figure out how to get back?I was worried they would continue to yard jump into other yards with dogs so I clipped their wings... I looked up a video on youtube, easy and problem solved. We are a small two chicken operation and my backyard gals free-range in the backyard during the day if we are all home, on hawk-watch. They are cooped each evening.
