Im fairly new to backyard chickens and i have a chicken that hasnt moved in a while and will kick dirt on her. I know it is normal for them to take dust baths. She isn't injured but i was worried because she has bean dust bathing for a while now. probably like an hour. Please let me know if this is normal.
You might want to check her for a mite infestation, but such behavior is quite normal - frequently in conjunction with sun bathing.
