She was eating and perching till today. She threw up this morning and now is on bottom of cage with drooping feathers. No signs of eye or nostril problems, poop looks fine, eating well, drinking a bit more than usual. But can't stay awake unless hubby is next to her and then she is "acting" fine. I am afraid it could be what Gizmo died of and I spent thousands on him to help him. We just can't do that with Fifi and love her so much. I am so sad. It doesn't fit any sickness I am aware of. She has not thrown up again today. Will be watching tomorrow and may take her in. I am afraid it may be too late for my grey.
