Ok, I gave up on the ivomec and have given up on the Eprinex for now. The locals look at me like I'm from Mars when I asked for it yesterday. So I picked up a bottle of Wazine which is the only thing I could find around here. I will order some Eprinex to keep on hand. But my birds need wormed now so I have to go with what I can get quick. So, if I understand the directions correctly, I take away their water in the evening then use the Wazwater as their only source of water the next day at a rate of 1oz per 1gallon water. Then go back to plain water the next day. Throw away their eggs for 2 weeks and do this treatment once a month every month. Right? So for 2 weeks of every month I toss all the eggs. I hope that somewhere I got it wrong cuz this just doesn't sound right. HELP!!!!!!!! And what about a regular worming routine using different products like, Wazine in March and Eprinex in October? Good idea, bad idea? What do y'all do?
