I have a chicken with an overload of worms which happened rather quickly, I'd say. This is my first go around with anything worm or parasite related. I have ordered Wazine and Ivermectin. I planned to treat the whole group with the Wazine first, wait 10 days and then treat her specifically with the Ivermectin. The problem is that the Ivermectin has arrived but I just got a shipping notice that the Wazine may not arrive until late next week. Not happy about it! I don't want her to suffer longer. Does anyone have advice, or experience with using the Ivermectin first.... Before a dose of Wazine... And it having bad results? Killing the chicken? I just need some opinions. Thanks so much!
