Hell again All--I posted a while back about my hen having feather mites. I've since treated her and my entire flock with elector PSP, and I think they are gone. My question is--will her tail feathers recover? They were really chewed up from the mites, and they still look terrible. Her wing feathers still look bad, too. I've googled the heck out of this online and can't seem to find anything about it.Should I be concerned? How long until the feathers recover? Perhaps I should treat her and the others again with the elector to be sure they haven't come back? Thanks for any help or thoughts!
