I used a solar fence charger for my pigs. Worked well.It got down to 34 last night and we had a hard frost. The piggies didn’t want to come out until about 9 am even though it was light at 6:30. They are now happily eating clover and exploring their pen. They are 2.5 months old and really tiny.

The hog panels seem to be working fine for now. I don’t know how I would get a hot wire over there. We’ll be keeping an eye on them for now.
