My new 7week old chick came to us with lice. The photo shows the carnage on the bottom of the bowl she was bathed in. There were plenty more that went down the drain. She'll have another dip next week, and a week after that. I used neem oil (from the health food store), dawn dish soap and warm water. I mixed then up and dunked her for 15 minutes. Most of the lice were dead within five minutes. I used an eye dropper to apply the mixture to the feather shafts that were not submerged. It works!
