What are the most common respiratory problems among budgies? I've read about aspergillosis but it is mainly linked with larger parrots in the articles. I had a bird that died last year from an identified respiratory problem which did not respond to broad spectrum antibiotics for very long. I'm sure my bird had aspergillosis when I purchased it. Are budgies prone to getting this disease?

 

And I've been reading about vitamin A deficieny. It says that birds that are deficient have white spots on the nostrils, mouth and eyes..it's not too descriptive, where exactly on the eyes and is it inside the nostril and mouth?

Vit A deficiency is one reason why a bird can get resp issues, I believe another one which is why I believe Pretty died is inconstant tempature in their enviroment and being too cold along with drafts. Pretty passed away suddenly from a respiratory infection and Merlin was just fine. I have learned to keep the room he is in at a constant 75 degrees F and no cooler.

I think respiratory problems are the most annoying disease a bird can get in my opinion, it's the only disease that's caused problems for me and my birds. The budgie I had was given baytril injections, ivermectin and clavicole or something like that and nothing kept the problems away. Baytril gave him a speedy recovery but three weeks later he was as sick as could be again, he died eventually, it was a really vicious respiratory problem that would not go away so I think there is a good chance it would have been aspergillosis I think the place where I got him from did not have very clean water, it's always a problem
