Found this coop freshener at TSC. Is it safe for chicks?

It looks very similar to Dookashi which I use in my brooder with a deep layer of pine shavings for my 4-week old chicks. They do try to eat it when I add it to their litter so I wouldn't use it for tiny chicks as they might ingest it in lieu of food.
