So I butchered a cockerel and discovered roundworms in the intestines ( it creeped the heck out of me at first). I know there's medication out there, but I was wondering what types of natural ingredients do people use to rid round worms & other internal parasites in their chickens? So far I've only read about garlic and apple cider vinegar for chickens, but researching about roundworms in humans, there are plenty of other natural remedies for internal parasites. I would assume these should work just as well for chickens, no? Has anyone tried other natural ingredients? Example of some other herbs / natural remedies include: Thyme : effective in hook-worms, roundworms, thread worms, and skin parasites. Ginger: roundworms , blood fluke , salmonella. Pumpkin seeds: round worms and tape worms Wormwood: for roundworms, hookworms, and tape worms Coconut: treatment for roundworms Pomegranate roots and stems: has punicine, which is highly toxic to intestinal worms. Papaya: enzyme papain helps destroy roundworms. And the list goes on!
