I am having an unusally bad outbreak of mites... red and northern. I think. Got some liquid ivermectic. Think I have seen posts about using this. Any help with how to give... oral... topical... injection, dosage... I have banties, ameraucanas and orpingtons. Repeat??? and how long to withhold using eggs.. Also what is best for treating coop? I am pretty sure somebody will have some answers... as the smartest, wisest chicken people on the planet are right here!! Thank you in advance for any help for advice.
