I am sure there have been threads on this but I couldn't find one... I have a broody hen (been on the nest for 3 weeks - eagerly waiting for hatchlings!). Today, when my hen was out and I handled the eggs, I saw a yellowish crawly on an egg! My guess is that it's a louse. My hen takes daily dust baths but I am sure that lice will still populate with her sitting 23.5 hours a day in the nest. What else can I do to stop the lice from populating? Will they start being a problem for my other 7 chickens that roost separately but in the same coop?
