My dog has an appetite for chicken poo. I'm not sure why. I have two dogs and I've only noticed one eating it. He doesn't eat dog poo though. So how unhealthy is it for a dog to eat chicken poo? extra info: my chickens are only about 2 months old, and never been dewormed. My dogs are wormed monthly. The chickens free range in the same area as the dogs. The poo eater is actually the dog we are hoping will be a guardian dog one day.
