Might it be worms? I think I'll have a test done. Better to err on the side of caution. And, to answer an earlier question: no, she isn't used to being handled. She's the most skittish and stand-offish of my flock. The others all eat from my hand and jump in my lap. Not Iris. She was also very needy as a chick. She cried a lot and wanted a lot of attention (ironic considering how little she wants to do with me now). I will update as needed for more input. Thanks, again.
