I'm beginning to see a pattern here:
The only hitch was that early in the process, Nieuw apparently jumped the fence into the next paddock, although neither of us saw her do it.
One section of fence sagged enough that R6 Nieuw got out.
Yesterday, I caught her in the act. She's been going under the fence, not over. Since the bottom-most strand of the electric netting is neutral, she's discovered that she can flip it up with her nose and scoot under, especially if the fence is "floating" on top of heavy vegetation. So yesterday I had to chase all the goats back into their previous paddock and then use my scythe to cut a fenceline for the netting. Once it was flush with the ground, I staked down each section with tent pegs. It seems to have worked, because everyone was still in their paddock this morning.
Also, Bubba seems to have figured out not to stick his head through the fence, because I haven't had to rescue him since the last time I posted about it. So he got a reprieve from wearing a pvc pipe across his horns.
