New carpeting in pig pen again

It was time again to replace the "carpet" in the pig pen. The recent rains and time since the  last bedding change was making a soupy mess. It wouldn't be good for the next set of baby piglets (due soon) to be born in wet cold mud. So... here is another ton of hay spread out across 3/4 of the pen. The shelters are about two feet thick, the rest is anywhere from a few inched to a foot thick, with some mounds left deep for them to dig in.
