I'm not saying that your fence will deteriorate, I'm saying that eventually you will have a fox that actually wants to eat your chickens. Electric netting is better than nothing, but it is doubtful that a fox or coyote would ever allow themselves to be shocked by it, they can sense electric current from feet away, if they are somewhere that electric fence is common, they know to jump instead of crawl. Unless your fence is 6 or 8 feet tall, all you are doing is keeping out the ones with full bellies.
I was directing the durability comment to Catnip. But, you say, that I will eventually have a fox that wants to eat my chickens. I've already been through that, that is why I bought the fence. I lost 16 birds to them, in two separate day attacks. So yeah, I know the fox really likes chicken dinner (Or lunch). Where do you get the info, that the fox can "sense" electrical current? They "sense" the fence, when they get in excess of 8000Vs to the face. That's when they sense it. You video shows the animal jumping over a standard type of fence. They see a clear top rail, they have to clear. So an animal sees the birds in the yard while he is running up, then he sees the fence, sees the solid top rail, then just jumps it, on his way to a free lunch. The netting does not have that. He'll see the chickens/lunch, and as he runs in for his attack, he sees this netting in his way, with no clear top rail to jump. So he'll stop, and check out what's in his way. As they always check out things with their noses, he gets a painful shock to the face. After that, all he is thinking about, is getting out of there.
As I posted, I have fox that love chicken dinner. If they are so clever, why haven't they figured out a way to defeat the fence? I mean, the easy meal is right in front of them. Why don't they just jump the fence? How come none of the other animals around here, just jumped over, and had a plump, easy meal? Because animals don't have critical, problem solving thought. They approach what they see is a easy meal, see some flimsy looking harmless netting in their way, check it out, and all of the sudden suffer probably the most painful thing in their lives. Now they will just stay clear. Have you ever had an electrified poultry net fence? I do, with years of success. If the fence is properly maintained, and kept properly charged, you won't have a loss to a ground based predator. I've read on this forum, where somebody has not had a loss in something like 15yrs, because of their electrified poultry netting/fence.
