I was reading where a moveable pasture for pigs could be made using 5' sections of re-bar pounded into the ground a couple of feet then covered with a 3' piece of old garden hose as insulation. This seems pretty cost effective providing you can purchase or have a charger. Any thoughts? How to attach the tape to the hose so it won't move up and down or come off? It's got to be sturdy - it will need to be uprooted and moved regularly. If I can make this work using a portable shelter and a feed trough INSIDE the fence, and a water barrel with nipple outside the fence, I might be able to take advantage of some very inexpensive (and inconvenient for their owners) piglets in my neck of the woods! I'll have to haul water to fill up the barrel though - bummer. Thanks, Liz.
