My neighbor that used to have pigs is the one that suggested putting wood down in between the two layers of the pallets to keep the little ones in. He is the one that helped us put it together with his tractor after one pallet fell on my back while my husband and I were trying to stand them up. We didn't have enough wood laying around, but I had stacks of the blocks. Some are 8x16 and some are 18x18. I figured as they dug under the edges, the blocks would be heavy enough to keep falling deeper so they couldn't get out. They have dug some holes as much as 2 feet deep and haven't escaped. We had 4 pigs in there originally, but 2 went to slaughter a few weeks ago. There are still 2 left in there. My husband used a backhoe and dug a pit behind the pen. Then he took out 1 block. When we get a lot of rain, like we have lately, it is a self cleaning pig pen, ha ha. He gets in there once a week to do manure duty also. We give them straw for bedding, there is a 50 gallon water trough, and the bunk feeder shown in the picture to hold the feed, bread, and whatever else they end up getting. He cut the legs off the bunk feeder, buried it up to the bottom with sand, then took metal strapping and attached it to the inside of the pen. It is sturdy enough to be used as a bed by them, which happens frequently.
