Bagheera keeps shaking her head. I checked under her wings and around her vent for signs of lice or mites and didn’t see anything. Do I need to take a better look? My flock has something respiratory, but nobody has symptoms right now. Last weekend I looked in Bagheera’s mouth and she looked clean. I thought she might start molt when I noticed this behavior, but she hasn’t started yet and she still likes to cuddle.
