So, I live in NC and we have mud mixed with clay. My girls (24) have a large coop (100squ ft), a covered run with dirt floor (no mud - we have 1 foot concrete walls at the bottom) (10x12'), and a 25x25 outdoor uncovered run (covered with bird netting but no roof). They share this with two lazy wethers (neutered goats), who do nothing but hang in their stall or on the two 4x4' platforms. The goats hate mud. But our girls love it. And we've had sooo much rain. My boots sink down 10 inches in some places. It's a slanted piece of land, with two ditches with rocks at the bottom, but it's just not resolving. What can I put down? Crusher stone? What works well without cutting up chicken feet? My girls are getting sores on their feet from staying in the wet (it's been in the high 90s, so they adore the cool wet places).
