The straw was a good call, I put down a LOT!!! but with the rain it so packing down,, the hens feet are much cleaner.My silkies have little houses. The large fowl have a dirt floor. I toss shavings in occasionally. It stays dry on top even though we have a high water table. Run is 15x35 and I put 3 to 4 bales of straw out there every 3 months to prevent it from becoming a mud pit. It's just bare dirt and rock come summer so they can dust bathe to their hearts content out there. There are a lot of worms.
