I pluck them out. It sounds mean, but I just pull out the feathers at the base with all of the stuck eggs. Then throw them away. I pull out feathers that get feces stuck in them as well to keep the vent area cleaner in the really fluffy ones. It is a moment of sting so I do not have to deal with bathing. My chickens are not handled that much, so they do not enjoy bathing- at least they are not used to it like some of my 4H buddies chickens. I also use pyrethrin (poultry dust) powder or carbaryl powder (sevin) every two weeks for a month or so if I see lice. DE has never worked for my birds, and it also gives me a rash. I gave up on it after a trial. Didn't get rid of lice and didn't get rid or roundworms. The concept seems ok though- killing insects by dessication and mechanical trauma to the skin. Borax powder is supposed to kill flea larvae by the same action when you rub it into the carpet. I just didn't care for it on the skin or feeding it out. Jess
