I went into the coop to clean the poop boards day before yesterday and there was a poop that looked like a MEDUSA HEAD. Nice firm poop with about a dozen worms sticking out just like Medusa's head. I am presuming these are round worms, to me that is what they looked like but they weren't moving. Before any one asks I didn't take a photo as I don't have a mobile phone. I have never seen worms in the poop before so was very shocked to see this, didn't see any last night. Can Panacur be used to worm with and will I need to withhold eggs?
