Very wise, Wise Woman.
I, too, was swayed by the sand is bliss camp. Honestly, I really do understand why people love it. But there are hazards, and it is indeed wasteful.
But one argument I read from a city dweller is a small backyard and problems maintaining a compost pile. For the sake of appeasing the neighbors, she opted for sand, and for her busy lifestyle, it made keeping chickens easier for her.
I'm here, though, to encourage people on the fence to start with shavings or mulch. It's a simple step to convert to sand, but not so simple to put that wagon in reverse.
If you're short on mulch materials, ask your city about leaf cleanup in the fall. You can gather several bags for free, or pick up pre-bagged leaves, and use them in the coop, along with other things like grass clippings.
ETA: As for how to get rid of the sand, post it for free on Craigslist. Someone will likely take it for an underlay on a driveway or pathway, even if it was used for chickens.
