He's traveled before but
I have twice taken my parakeet on a 6 hour drive to another state. Now I am moving there permanently and he will have to make the drive again. Every time he has been a very good traveler, but the last time, on the way back, he started to make this strange kind of chirpy noise. Not so much that he was in pain, but like his feet hurt or something. He is 10 years old, and I adore him, but want him to be comfortable. What could that chirpy noise mean?
