We are ready to turn the 4 little piggies out onto the pasture. I need to build a trough to hold their supplemental food and have seen a few designs to try, but thought I'd ask the experts! What I've read so far is a 55 gallon drum split lengthwise with "feet" of PVC pipe under the curve. The other contender is the v-shaped 2"X12"X4' with sides that both the end caps and the leveler. Other suggestions? I'm looking to keep this project <$40 Also, favorite containers for water? They flip all the tubs I've given do far, but I could try to weight them with large rocks outside?? Thanks.
