My hen roosted out side last night and she somehow pooped in her feeder, so when I went to wash the feeder out, I noticed these cream colored skinny long worms in the poop. It was definitely worms and they were pretty long and there was about 8-10 worms in one thing of poop. Also she hasn't layed eggs in two weeks. Could this be a cause of worms and what can I give her to clean out all the worms?
