Lol Fences work? Mine are great at flying they even get on the roof of the house when it strikes their fancy.
Ugh! No, they don't work as well as I wish they did. I have three or four that basically come and go as they please (at least they get back in on their own). Then there are a couple more that seem to get out a couple of times a week, and we have to go catch them and put them back in. The ones that get out do seem to stick a little closer to home, I think, when most of the flock is still in the fence.
