I have electric wires around my coops and pens. The predators know they're there. Here are a few links that may help and save your birds from predators.

The coyotes know the electric wires are there.

This is my outer pen. The white lines around the bottom of chicken wire is hot wire. Most of the time predators investigate with their noses and have 4 feet on the ground so when they touch the wire they get zapped. I have seen places on the back side of my pens where there is evidence of something attempting to dig under the fence but didn't succeed.

This is the fence charger I had until a lightning strike which also took out our well. I had it for several years. Now I have a fairly inexpensive one but it works well and works on both AC and DC which is good for Florida. A few years ago we were hit by a hurricane and lost power for a week. I think the predators knew that the wires had been hot so they didn't attempt to broach them. Now, I have this HiFence and so far it works well. I'm surprised as it didn't cost that much, but had pretty good reviews. I wasn't interested in solar, but if we do loose power for an extended time, I can hook it up to a battery.
