I paid about $600 for the net electric fencing, the energizer, jumper, etc. I never could get it to work properly b/c of grounding out on grass or places where the fence would sag a bit b/c of uneven ground. If I took the connectors apart where the sections joined down the fence line, it would give a jolt that would make you think twice about touching it again, but I could grab it anywhere along the netting and nothing -- sometimes I would feel just the slightest pulse. I now use the webbing fence as extra free range space in the yard on days I'm going to be home, and on days I'm going to be gone I leave them in the big chainlink run. I've considered putting a couple of strands of electrified wire around the outside of the chain link for some added protection. The energizer I got from the Permanet Co. is supposed to be the right voltage/side for electrifying 150' of fence to protect chickens and keep them in, according to the customer service rep. In retrospect, I should have gotten a stronger one because I'm much more concerned about keeping other critters OUT than I am in keeping the chickens in...
