From what I read this may be pneumonia. I have some Baytril ordered from a bird place but it won't be here till next week. When we raised our 3 babies I was concerned about aspiration and pneumonia. Not sure that is what is going on now, but seems like similar symptoms. Sleeps in her house all day, seems to be opening and closing mouth regularly and yawning some. I guess mouth breathing. Sometimes when I hold her she is shaking, not always but sometimes. She makes a popping sound sometime when she breathes, but I don't hear a regular click. We worked hard to keep this runt alive. She was slow released but only made it outside for about 4 weeks before she was near dead and we decided to give her a home. She is now 2 1/2, can't jump much and has only half a tail. My daughter is a Dr and I could maybe get some human meds, but doseage will be an issue. Thanks for your help. I want to keep her going.
