The poop does not decompose in sand, it just sits there until it gets wet -- at which point instead of odor-free compost you get rotten poop.
Sand is favored by people who can keep it dry and are diligent pooper-scoopers.
I'm too lazy to scoop poop and live in a hot and steamy climate with rainy, wet winters. Sand is my natural dirt here -- the sand that gives the Sandhills it's name is like fine beach sand.
Deep litter is odor-free when properly managed because it's a form of composting that balances the "green" -- high nitrogen -- chicken poop with the "brown" -- high carbon -- litter to create compost. Poop in sand is just green with no brown so it can't compost.
