I have a total of six chickens, all hens, one Buff Orpington, four Rhode Island Reds, and one that I'm not sure about. Of the ones that I do know, they aren't quite laying yet, but are showing signs that they will be, the last one is about 3 weeks older. They are all happy and healthy, and I leave them to roam around my suburban back yard while I'm at work and no one is home. Unfortunately, they have taken to jumping my fencing (regular chain-link) into my neighbors' yards, and while my neighbors don't mind, I'm afraid that they may let out their big dogs, or they might just leave the backyards and get into the road. Is there any way to curb this desire to leave the yard? I have taken to piling leaves for them to play in and hiding food for them to search for, and it helps, but is not quite doing the trick... Any ideas?
