Hurricane Hermine blew through Florida today, but had sent plenty of storms ahead in the days before. I brought my chickens inside on Thursday because the whole back yard - including their coop and run - were flooded six inches deep. Most of them wouldn't get off the roost and the two that would were soaking wet when I brought them in. Now that the rains have moved on, most of the water has drained away, but there are still a few puddles 3-4 inches deep and the mud is very soft in most of the yard; I sink down a couple inches when I walk on it. Normally drainage after even heavy rains isn't a problem, but we got a LOT more than our usual amount of rain in the last few days. What can I use to dry up the water that's left in a way that's safe for my chickens?
