A bit of background: Chestnut is about 4 years old, I adopted her when she was young, from a breeder who couldn't keep her with the rest of the birds because of a wonky leg. Despite not having use of one leg, she has thrived and learned to do things in her own way. She's also developed quite the personality!
Up til now, she's been fairly healthy except for the occasional trouble passing eggs (unfertilized; she has a cage to herself) but she always recovers and is back to normal within a day or two. Four nights ago, out of nowhere, she woke me up in the middle of the night making noise.. a loud, painful screeching sound. The best way I can describe it is similar to when you squeeze the air out of a balloon. She made the sound a second time a few minutes later, so I got up to check on her and she hopped up on the edge of her nest and started talking and beeping to me like normal. Next night, same thing happened.
The third night went by without any problems, and I actually thought whatever it was had cleared up on its own.. Last night I was proven wrong, when I woke up to her having a very bad coughing fit. I sat watching her for an hour, and she'd switch between soft coughs in rapid succession, and the loud screeching sound. She tried to tuck in and go back to sleep, but after a few minutes would start back up again. I noticed her beak hang open each time and thought it looked like she was retching or trying to vomit something up, but nothing came out. Soon as morning hit, she was alert, active, and talkative as usual. It was hard to believe she had looked so sickly just minutes before!
I took a video to capture the sounds she was making: https://www.youtube.com/watch?v=C_-5Lv3Pfcg
Right now I'm trying to find an avian vet in town, but I wanted to see if I could also get some advice from others who have kept finches and might know what's going on. Apologies for such a long post, I tried to be as detailed as possible. If there is any more info needed, let me know. Thanks for reading!
