One of my babies, BBQ, is doing something new over he past few days. She nestles down an acts like she is dustbathing, and then rolls off to one side (always her right side). Now she isn't completely on her side, but is kinda laying on her wing. SHOULD I BE CONCERNED???? I have never seen a bird any where do this, none of the other ones are doing it, and she doesn't seem ill..... She is eating and drinking fine.
