Now I'm not quite sure what we're talking about. I thought egglady meant the soft electric mesh which is moveable, not rigid stock fencing. The moveable stuff is what is not suitable for horned sheep as they can get entangled in it, so stranded is better there. We use the rigid stuff - Rylock - with one or two tensioned strands of plain wire along the top. Lambs can get stuck in that and sometimes break their horns but only occasionally and they soon grow out of it. We started with high tensile stranded fencing when we arrived here and our sheep just walked straight through it - it wasn't electrified. Now we find that Rylock as described above suits us fine, with no escapes and no strangling.
