Cleaning out our chicken tractor's roosting area today, we found some tiny little flatworms! -Smaller than a grain of rice, dark brown in color, undulating movement. -Mostly seemed to be hanging out underneath the dirty newspaper bedding. We, like many, are new to hen-keeping, and want to give our ladies the very best in health care. Even if these worms aren't intestinal parasites, we will probably dust with food-grade DE in the next few days. The weather has been warm and wet here in Austin, Texas, and insect life has been going crazy lately. Anyone met these critters?
