Budgie is shaking and whimpering.
My budgie is about 8 years old and just the other day she started making strange noises. Almost as though she's whimpering. She is also shaking. Her tail mostly. It is going up and down, and seems as though it's vibrating.
She is still eating, flying and chirping as usual, although she seems a little more persistent to spend time with me. I've read that she might have a respiratory infection, but my mum says that a vet can't help. Do you know what might be going on? Should I take her to the vet?
