I'm all for wing clipping. It's easy and it supposedly keeps them in. Maybe they will be less able to escape predators that could get in, but I consider a neighbor with a gun a predator too. My area is crawling with coyotes, foxes, rattlesnakes and the occasional mountain lion which most recently killed a flock of emus and a mini horse about a mile from me. However, I consider my dogs and my neighbor's underfed dogs as more of a threat. My chickens are locked up tight in their coop every night, so I'm not as worried about the night time predators as much. I guess you have to decide which is the lesser of two evils and that the only way to be 100% cautious is to put netting over an enclosed run.
