That is what I like to use in my covered (chicken) runs. I essentially do a modified version of it... because I pickup whatever dropping I can identify, even after they've turned into flat grass covered looking dry pancakes. I aim to make the floor like the forest floor... a mixture of pine needles, dry leaves, grass clippings.. type stuff. This majorly prevents smell around the edges when it rains compared to when I had bare dirt or sand/pebbles. It feels spongy to walk on but doesn't get muddy. It has taken quite a while to build it up for me.
