Thirty additional meetings over a 2 month period at work for strategic planning? Sounds like a job security to me. I think Bagheera will be fine. I dont believe there's anything serious going on. She mightve inhaled a feed granule and it might be working its way into or through a sinus cavity. I've had that happen in one of my hens, a red star a long time ago, and there's nothing that can be done unless it comes up just under her skin on one side of her face. It'll appear as a white in color "zit." It can be removed by minor surgery and applying neosporin afterwards for a few days, no problem. You mentioned something respiratory going on in your flock. If that's the case, there's the possibility of mucus located in the trachea. They try to loosen the mucus by head shaking in order to properly breathe, you would most likely hear wheezing as well. That's if it's not small flying insects bothering her.
