Thanks guys, I know that testing is expensive. We take our parrots to Deborah Monks at Brisbane Bird and Exotics Veterinary Service and I'm fairly sure she would do this testing for us if we asked. I would say that she only made that noise for maybe half an hour yesterday. But the fact that she made it all indicates possible illness is that right?
Not necessarily , she might have had something caught in her throat , without hearing it and knowing the exact circumstances we are just warning you of the possible dangers to your flock. Keep her quarantines with her buddies , watch her poops and for any signs of facial swelling or mucous . Unfortunately the only way to test for many avian diseases is a necropsy.
