I was finally able to see the videos by clicking on the numbers instead of the red arrow. She seems very weak, and some of the noises may be normal, but in the one she is sneezing and gasping, and swallowing mucus that is coming down from her sinus cavity. I would be tempted to repeat the doxycycline at 40 mg daily for 5 more days. She could have a virus or even a fungal disease from mold, but the doxy could treat her for MG. Her beak is so long, that she might eat better with a trim. Getting another person to hold her wrapped in a towel and having the nail clippers right there, you could probably do it quickly so as not to stress her too bad. As weak as she is I am not sure that she will live very long. Sometimes we can find out what was wrong by having the state vet do a necropsy. I wish I could help more.
