I picked up straw for my brooder boxes, and have A LOT left over. So, I put it in my coop, and well, I kind of love it. Cleaning it out required just a muck fork and the whole bottom of the coop came in one pull. Replacing it I just grabbed a flake and spread it back out instead of wrestling with a bag of shavings. The chickens seem to enjoy scratching around in it. Originally I was just doing this to use up what I had, but I think I might stick with it unless there is some glaring reason I shouldn't. I have a Nestera coop, so the coop is all plastic.
