some are really small, so small i can barely see them even with reading glasses. The ones in this link are large:Is it alright if the drop on the head gets on the feathers? Also, I couldn't find any pictures from Google of face and ear lice in peafowl. Would I be able to see these on my birds or are they smaller than chicken lice and hard to see?
