I know, I feel awful too. I didn't check Screwball when my sister brought him over. I trusted that her birds were clean. I did check the ducks and the Black Orp cockerel before releasing them into the yard, they were from outside sources so I always check for parasites. But my sister ends up being the 1 who gave us mites. So far Screwball is the only one with mites and eggs. Don't see any mites crawling on him at the moment, checked this morning and put him back in solitary. But his butt is now red and irritated, which it wasn't 2 days ago when I treated for mites, and I can't get the eggs off him. I treated with Eprinex pour on, it does internal and external parasites. I have to do it again in 10 days, but what can I do to relieve the itchiness?
None of my other birds shows eggs on their vent feathers, so I am hoping I caught it early enough to prevent mass infection. I gave everyone a treatment to be safe.
