I want to worm my birds because their weight is starting to drop but they're still eating well. So I think I have a worm problem. Last year I used Wazine, so I'll be switching to Ivermectrin this year so I can give those blasted pests a run for their money. If I worm now, will I be able to incubate the eggs laid by the wormed hens? I know I can't eat their eggs, but are they still good to hatch? Also, how many doses of Ivermectrin does a bird (both LF and small bantam) need? A single dose, or one dose a week for two weeks, or something else?
