Just got back from the vet with my bird.
She's completely, 100% healthy. I have not taken her in before, so I figured I'd take her in since she has been scratching her sides with her feet once in a while, which I've never seen her do and was afraid she might have some mites or a sore that is irritating her.
She's a big girl, apparently. Most parakeets weigh 30g he said, and mine is at 45. He's not overweight, in fact she's extremely fit (she flies constantly for exercise), but just in general she's big.
It cost $70 total for the checkup, and some food I purchased for her there.
Now I'm going to go get some grub.
