You can also use Safeguard paste as a follow up to the wazine in about 2 weeks. Use a BB size piece of the paste and put it on the side of their beak. I prefer to use Ivermectin pour on as a follow up to wazine. Ivermectin wont kill tapeworms,but it kills pretty much everything else. When I first used wazine, I also noticed that it quickly transformed the hens from being lethargic to hens acting like chickens should.
