This wormer is for use in drinking water for the removal of large roundworms from chickens. It removes roundworms only--there are many types of worms that affect chickens, so we recommend you contact your local vet and obtain a fecal smear to make certain you are using the product that will help in your situation. Even vets who do not specifically treat birds or chickens can often perform a fecal smear for you.
