Our little piggies have settled in and have stopped running and hiding when we approach. Now they come running to meet us at the gate where they line up waiting to have their head scratched. They also come running when we call out. They now weigh about 50 pounds each.
We constructed this automatic water from a 55 gallon barrel (it had held 
peppers and is food safe) and four “pig nipple drinkers” set at 12 inches from the bottom of the barrel. Water flows while they apply pressure to the lever, then stops when they stop drinking.
Total cost for the automatic watered was under $50.
Next project is an automatic pig feeder.
