That's outstanding information that @coach723 put out for you.
Additionally, keeping everything as dry as possible goes a long way in preventing birds getting worms.
Sand is best for keeping everything dry, think "beach." I have sand in all my pens, coops and some of the nest boxes. Sand dries quickly after it rains and doesnt wash away like dirt or mud. There are no nasty mud puddles for birds to drink out of. Sand also deters parasites.
Deep litter is a hot bed for capillary worms, especially if you live in a warm/humid climate.
