Parakeet heavy breathing - tail bobbing
About a week ago I took home a parakeet that was abandoned at a pet store I am working for. She was left with us in an extremely filthy cage so it seems that she has suffered some neglect. I have bought a new cage and everything for her so that she has a clean healthy environment.
What now concerns me is that she breathes quite heavily, with her tail bobbing up and down but with her beak closed. I am not exactly sure how old she is but she definitely is an older parakeet. She seems to have a healthy appetite and is starting to sing now that she's becoming more comfortable, but stays on the top perch for most of her time. Should I be worried about the breathing? And is there anything I could do to help her?
