I tried sand on a cement floor for about a year and I didn't like it. Used deep litter after that with both straw and wood chips. Despite interweb claims, deep litter does not produce heat in the winter or any other time of the year.
When I moved up here last fall I did not have a proper coop. It is a Harbor Freight portable garage set on dirt. There is a good 6-8 inches of straw on the floor. And I had an ammonia odor recently. The cause is saturated ground under the straw. There is a low spot and the rain and snow melt collected there. Today I pulled out all of the straw and it was a nasty, wet mess. I'll move it to the hot compost pile next and run it through the shredder before adding to the pile.
Within the next few days I should have a proper coop built and I will do deep wood shavings. I've had the best luck with that. A good dose of PDZ too.
Good luck.
