Our Splash Cochin roo, Foghorn, is about 4 months old. We bought him from someone on BYC. For some reason, we've noticed how light he is. He seems healthy, and he's eating, but he seems so light-weighted and skinny. I'm worried that he has worms. So, I have several Qs: 1. Is this a sign of worms? Are there any other signs? 2. Can you tell if a chicken has worms by looking at their droppings? 3. How do we worm him? 4. Where do we get the worming medicines? 5. How much does it cost about and where can we get it? 6. How much do we give to him? 7. Is it fatal to not worm him? What will happen? Thanks!
