My hen laid a pile of poop with long, thin, angel hair pasta-looking worms. From my research they appear like Round Worm. I am learning that Round Worm is quite common. I just treated my entire flock with Ivermectin orally. Here are a few questions I hope someone can answer: - How long do I need to throw out the eggs? - Should I see my hens pooping lots of worms? - How do I kill any eggs that may be out in the runs in their old poop? - How do I keep my hens from re-infecting themselves? This seems like a very challenging health issue to resolve I was using DE year round in their food but that obviously did not work. Thanks for any insight you have!
