Electric poultry netting is moveable w built in posts, so you can easily move chickens to fresh grazing. I have a friend who has been using it for years. It's only the 42" high, but they don't fly over it. The first year she trimmed wings, and they got used to thinking they can't fly. New additions to the flock have just gone along with that assumption. If you Google electric poultry netting, you'll see what it looks like....What does that do?![]()
