tbostic91, sometimes this can happen when a dragon gulps his food. If Phoenix Worms are not chewed, it's harder for stomach acids to digest properly and whole worms can appear in the feces. A solution is to only feed a few worms at a time to slow down the feeding process. This will ensure that teeth pierce the worms before swallowing. Also, the larger size worms are more easily chewed (large Phoenix Worms are only 3/4" long). Usually dragons outgrow this tendency to eat fast as they mature. If this doesn't work with your beardie, you can pin the prey before serving (poke a needle into each worm). This is what dart frog hobbyists do before feeding their frogs to ensure good digestion.
