Fact
if there on dirt. Skip the pool. They'll make a wallow. Also if on dirt run a hot wire. If your only having two and butchering yourself it shouldn't really matter how uour going to build the pen but should you ajve to load them on a trailer for a processor keep on mind you need a way to funnel them down and if they can see through it they're gonna try to push through it. As far as the water goes with only two pigs I'd probably keep your barrel with a spigot. If you run a hose two pigs don't drink enough to keep the line from being scolding on a summer day. Ymmv when you build your pen keep shade in mind.
