So one of the girls in my flock has worms and I am now treating the whole flock. I think they look like tapeworms as they look similar to when one of my dogs had tapeworms last summer. I treated the flock with wazine for 24 hours in their drinking water and they will need their next dose in 8 days. Will wazine solve my problem? What if in 8 days I use ivermectin instead of wazine?
