11 weeks old. not really growing. cannot fly, and barely tries. slowly getting more and more immobile. this past couple days has been a slow motion downward spiral of her ability to move at all. she is over-stepping when she does try to walk, topples over alot and is splaying her left leg straight backward when picked up. I have put everything close to her. eating, drinking, sleeping fine. I haven't seen any poop, but I am not looking very hard for it. Started giving her B2 vitamins this morning. I even soaked some food in it. What's wrong with her? Will she come back?
