I do and have never had a problem with my chickens getting out. And they can fly! I do have trouble with things getting in though... hawks. A friend of mine here in AK saved me a recycled fishing net from the dump. Wow! It was a great inexpensive way to cover the coop run (about 20x24'), and it went over all the obstacles. The coop's peak is taller than the fence. It just drapes over. I am not fooled thinking it would keep out a more aggressive predator, but it is going to be perfect for the "air-assaults" that I have had.
