I'm not trying to be snarky, but I can not believe that three feet of fence is keeping a fox out -- much less dogs, cats, coyotes, hawks, 'coons and possoms. if you haven't been hit by a predator yet, you need to chalk that up to LUCK, not your fence. I mean think about it -- these animals dig and climb trees. they're NOT going to be stopped by 3 feet of chicken wire. And with your chicken's wings clipped they're pretty much 'sitting ducks'. Or, maybe something else is keeping predators away. I just doubt it's that fence.
That said: I think that set up is awesome, and hope to have something like it eventually. at least in size ;-)
