I've had mine set up since Apr. I had 1 bird out of 19 go over the first day the fence was up. I clipped one of her wings and have not had any problems since. They are out there all day, everyday, and are totally content in there. Best thing, NO losses. I had/have a fox problem around here. Plus the occasional wandering dog. I seen a dog nose up to the fence once, he turned and ran howling from it, and didn't even look back till he was over 100 yards away. A hungry predator will tear through chicken wire easily, get something heavier. If you are going with some kind of a regular fence, give some thought to running a hot wire all the way around, about 6" off the ground.
