Interesting! I have heard others say the same thing. I just have breeders on Electric, and my experience is the opposite. I could almost throw my charger away sometimes I think. In fact, when I open a wire gate, it has to be feeding or breeding time, and they still don't want to cross that line....freemotion said:It has worked without incident with this year's four pigs. They also learn very quickly when the wire isn't working, which is often since they dig up stuff and push it against the wire, grounding it out. .
