Had a broody hen hatch out eggs 4 days ago. Hadn’t noticed lice or mites this spring, but we just noticed the babies have tiny brown bugs crawling around on their heads. What can we do, they’re only 4 days old? We plan to do spring coop cleaning and dust all the adult areas tomorrow, but what is safe treatment for the babies and mama? We brought her and the babies into a private space, in the garage, till they get a little bigger.
