Gracious. I was just heading out to treat the chickens for the first time w/ Ivermectin (used Wazine in the past) when I came here to double check the dosage. I notice everyone talking about Ivermectin Pour-On, Ivermectin Injectible....but nothing on "sheep drench", which is what my bottle says. Any advice? From what I see here, http://www.drugs.com/vet/ivermectin-sheep-drench.html, drench is given orally. If that is the case here, what is the dose to give?
