I love to let my bird out and free range by themselves without a fence(expensive and messy), but more recently I have seen predators coming around. I was just thinking would putting a strand or two a few inches off the ground around a large area keep them out and the chickens in? Could it hurt the chickens? It is electric wire that I use for my horses, I have been shocked by it before and it wasn't that bad. Any opinions are greatly appreciated!
