Okay, all of my birds have come from auction or private sellers near my home. I bought 3 young chicks (at the time around 2 weeks old) from the auction and that has been a month or two ago. These chicks have always been housed by themselves but haven't been growing right. I have a lot of chickens (well, for me a lot lol) and I honestly haven't been doing such great health checks lately because of work, snow, and caring for more pets than I need, lol. Yesterday, I finally picked one of these half-grown beasts up and saw a TON of "nits" I assume all over the base of its feathers. If one has it I have no doubt many more do too. I keep seeing info about Ivomec and Eprinex (sp?) but have no idea where I can get it locally, or how much to dose my birds with. I have many chicks that are from 2 weeks to 4 months old, and two adult flocks. Also, the majority of my birds are not huge but not bantams either. Maybe 4-5 pound range? I just need to find a way, besides bathing, to get rid of these bugs! I am so creeped out I wake up itching at night! I can't thoroughly bathe 30+ chickens in the end of December and not expect, even with blow-drying, for them to survive re-entry to the coop.
