Hi I'm relatively new to chicken keeping and had a few questions about chicken behavior. My youngest, Sky (a FBCM), is always quivering her little tail in nervousness when sh comes out of the run to free range it takes her abut an hour to settle down and she wont leave the side of the older chicks. Will this pass with time? Is this something I need to worry about? Is i a sign that she is not healthy? Thank you for your help!
