I recommend sheep/chicken mesh electric fence for pigs.
The night was stormy, a mini-blizzard. In the dead dark and strong wind, we went outside and wrestled the fence into place and plugged it in, then extracted the so-very-successful two-strand, in a big snarl, naturally. The pigs were willfully asleep. There was shouting, yet they refused to wake up. It was cold outside, they weren’t budging from the hay nest for nothing.
We caught them! The mesh fence works. In the morning, the pigs bolted away from the sight of us, ran into the fence at top speed ….and then sproing! bounced back. They tried it again and again, but eventually concluded that A: they don’t fit through it, past the nose, and B: the fence bites back.
I wouldn’t put it past them to figure out that only the horizontal strands are hot and selectively chew their way to jailbreak, but until then, our piglets are under control.
They are SO different than the last pigs. Besides being bigger when we got them, these pigs are feisty, and wild, with opinions. The pink pigs were totally into cuddling, crazy for touch, until they got too big for that to be safe for me (perhaps because of being weaned earlier?). We won’t be petting these guys anytime soon.
Most pertinently, the two-strand fence that failed so spectacularly this time worked with the last pigs. They screamed blue murder when they got shocked. These pigs don’t peep at it. We did have problems, but, the user-problem variety. We got lax about keeping it hot- it’s easy to find excuses to not carry batteries around – serenely thinking they’ve learned what the fence does, we don’t need to keep it hot all the time.
Pfft! The troublemaker noticed once, maybe by accident, that the fence wasn’t always hot. After that seed was planted, sometimes it’s off!, he felt it was a reasonable risk to test the fence, and did, every single day. The moment it wasn’t hot, grounded out by their rooting or a dead battery, he was out. Then, he would target the energizer, chewing and ripping the leads off and sometimes hiding them in the pig house. This practice definitely delayed the restoration of power.
A very educational mistake on our part. Won’t happen again (I’ve got a solar maintainer on the battery now – way cheaper than the admittedly awesome solar energizers).
This is the usual view of them.
Then they look back, balefully.
They wait until we leave, to eat. I’m conditioning them to the sound of approaching food, but so far we mean flee!.
They’re super cute, with their upright ears, long straight tails and white socks. Hopefully, they will come around and become friendly. Eventually.
In fact, recovering the escapee(s) only took three days, better than I hoped for after my initial googling.
