Yes I knew about the mesh would tape be ok?
They shouldn't get tangled in tape, but they might just walk through it if they are woolly and don't feel the shock. It's worth trying though especially as you have a stock fence beyond.
Womble - in our early days we once had the 'brilliant'

idea of making a small tupping pen out of electric fencing. What dunces

. The ewes didn't like the tup we had put in so they tried to leg it, straight through the fence. One of our sons found them and had to cut the fence to bits to rescue the ewes, all in the dark and howling gale. That's why I always make such a big thing about electric mesh. We do use it as a temporaray way of bringing in our sheep, not electrified, and only up for as long as it takes to funnel them into a hurdle pen.
