I'm just curious what makes you an expert over everyone else who has had years of experience in keeping and/ or breeding poultry?. You are being incredibly closed minded, or maybe just having fun arguing, idk. Are you a veterinarian? A professor of avian science or something? Do you really think avian veterinary medicine is that hard and fast, an exact science that can be treated only with commercial medication? Honestly, I don't know one veterinarian who has had any more experience or success in treating poultry than the average backyard flock owner, (and I have consulted various veterinarians a few times) so yeah, I don't have much confidence in them either. Poultry veterinary medicine is a whole new field that has never ever been explored prior to poultry becoming the latest fad in pets and back yard self sustaining hobbies. I do agree that natural remedies don't eradicate worms. But if someone wants to use natural products in their flock, there's nothing wrong with it and it may be beneficial in some ways. In my experience, once a chicken or peafowl gets sick, they are usually very difficult to cure. Unless they just have worms or coccidiosis, and even then....
