What could cause my bird's neck to fill with fluid?
(L.I. New York)
I have an eastern rosella and her neck keeps filling up with a greenish color fluid. I've taken her to two different vets and they've determind that it's not her crop filling up but fluid outside the crop. They've tried different medications but that didn't help.
Every 6-7 weeks I have to bring her in to get the fluid drained out of her neck. She's about 9 years old and I'm afraid of doing any kind of exploratory surgery not knowing if if could benifit her.
My vet put some of the fluid that was drained from her neck in a centerfuge thinking that if it separted and food particles could be seen that might show that her crop was leaking but the fluid didn't separate except for a very tiny bit of blood at the bottom.
Do you have any idea what could be causing this and what I might try to stop this from happening?
Thanks in advance for any ideas or suggestions.
