I know for certain the Shelly is still in that pasture. The little scoundrel followed me around all the time that I was working. Grunting from a distance, and occasionally sneaking up behind me to snuffle my shoes and generally startle me. I'm guessing that he won't be leaving Lava, so hopefully she is in that pasture too. Shelly is quite capable of leaving this area if he wanted to......thus another good sign that Lava is around since he's sticking around.
I've been putting out food in various locations. I've seen Shelly visiting all 3 buckets, but I haven't had a glimpse of Lava today. Perhaps tomorrow I'll spot her as I run the hotwire and clear more ferns.
One more day's work and the easy escape routes will be blocked. Then I'll work to get the fourth side secured. Wish me luck the Lava stays in that pasture for at least another day or two. By Friday afternoon the hotwire should be around the entire pasture enclosure. The hotwire with the field fence behind it should effectively hold the pigs in. I would have thought that the field fence and barbed wire combination alone would have worked, if I hadn't witnessed the hole they tore right through the field fence. Amazingly strong and destructive when they want to be!
