Hi all
One of my friends that also owns budgies is pretty worried about her birds, she said that they are vomiting, fluffed up and have clogged vents, she's also seen them "coughing" before which is what my birds did when they had psittacosis, I think it could be psittacosis, but im not sure, she's treating them for worms at the moment. Does anyone have any ideas as to what this could be?
