I'm very confused about mite treatments. Is ivomec drench for sheep something that can be used on my chickies? I saw somewhere on BYC to use Ivomec Eprinex for cattle. I'm not sure it's even something that needs to be done right now. I check the vent area on random chickens and haven't seen any. Is there any other area on the chook where the mites and/or lice would congregate?
