@Roosterbreaux, I've had my coop hot wired for 5 years. I've got zapped, my husband has gotten zapped, our dogs have been zapped, predators have been zapped, chickens have been zapped.......starting to see a pattern here? Sure people and animals make contact with it but it doesn't kill anyone or anything, at least my hot wire hasn't and it's strong enough to handle cattle and yes it's unpleasant but trust me, it only takes getting shocked once and human and or animal alike will avoid that hot wire or at least be careful around it.
Two years ago we had a female fox take up residence under a neighbors holiday cabin across the road from where we live. That fox had a litter of kits that she fed by decimating the local chicken population. Everyone lost birds. Either a few or like our immediate next door neighbor, who lost their whole flock to her. Everyone except us. Our hot wire kept her out of the run and coop. Plus my coop is metal clad and sits on a concrete slab. Nothing is getting in unless it knows how to use a grinding wheel or tin snips. I found adult and juvenile prints around the outside of the run in areas without grass so they checked it out more than once.
If a person is really worried about unintentional contact with a hot wire, there are signs you can get to put up alerting the public to hot wires being used. Of course animals can't read, but the goal of hot wires is to keep undesirable predators out and your chickens or other livestock safe.
