Fast fence electric netting

[canoetrpr]

Our backyard is fenced in with chain link. Not sure about the height right now but it is just regular height. Anyway, sometimes when the chickens are out they will fly over the fence to scratch in the backyard. I have never done it, but I have seen some people clip the chicken's wings and then they can't fly over. If you let chicken's stay out they will roost in trees, much higher than 48".

I guess that option is out for me then! I'd prefer not to clip their wings.
