If someone could be so kind as to describe (rather exactly) how to go about worming my chickens. I have 9 of them in a small coop. A few months ago, I treated them with Wazine-17, which I know is not a broad based wormer but it was all I could find locally, and I don't think it had any effect. "ivomec Eprinex" has been mentioned on this board as a better solution. But everything I find about it indicates bovine... is this what people are using? And if so, dosage, where to purchase, how do I go about trying this. The situation is general is that 2-3 of my chickens seem unthrifty--messy in the hind area... Thanks!
