I have two dead and at least two dying birds from the same symptoms as last time (this is first time I posted for help), the sounds they are making as they die sounds like gargling (?) when they breath, or sounds like breathing out through a blocked nose. From last time and trying to save one of them, I know their is water in their crops, and likely to be much fluid in their airways and lungs, they have watery discharge if they go to the toilet. I am not coping very well trying to decide if to put the two down, or try to save them. Last time I tried to drain some of the fluid repeatedly from one of the dying, it seemed to lengthen the life of the bird, but in the end it died just the same. Is there much I can do, or something I can try ? racking my brain here. not doing well.
