Bird hasn't got any respiratory problems, but is fluffed up
So I've got this problem...
My budgie (3 months old) has been exposed to a draft for quite some time (4 hours).
She stays fluffed up for a big part of the day (although she didn't do it before the draft-exposure).
I went to an avian vet, he listened to her lungs, and he told me that he couldn't hear anything off with my budgie's breathing. He gave me his phone number and told me to send him a vid of my budgie if she fluffs up (because she didn't fluff up while we were at the vet's, she was probs excited), he also gave me antibiotics, and told me that he will instruct me how to use 'em if he thinks there is any need for that. I'm pretty sure that the vet isn't lying about what he heard or anything... Because I went to the veterinary faculty here in Belgrade (Serbia) to get my budgie checked.
What I wanna know is what else could fluffing-up be a sign of if not of a respiratory disease.
Budgies sometimes fluff up when they are cold, stress or tired.
You only need to be concerned if the budgie becomes fluffed up and lethargic for a period of time.
This above is a good thing to keep in mind. A little fluffing here and there is fine. If she isnít lethargic, most likely she is not ill. Antibiotics should not be given unless it is absolutely clear that the budgie is ill.
