Is my 4 year old female parakeet sick?
Since this Monday morning, May 20, 2013, I observed that my female parakeet, who is between 4 to 5 years old, is puffed up and cannot walk properly, nor, fly up to her perch.
What is wrong with her?
Is she pregnant or is she sick?
Kindly note that I male parakeet about the same age lives with her in her cage for over 4 years now.
