for the past two days, my bird has been making weird chirping noises. not the normal kind, it sounds kind of like a motor, but not loud. i don't know how to explain it. is there any reason to be concerned. my mom also told me she noticed earlier today that he was hurt in his leg because he couldn't turn around and he was having trouble putting it on the perch. i checked up on him after school today and he was fine. i'm thinking maybe he was chirping weird like that maybe because he was in pain. any suggestions? thanks

( he seems okay now. i was playing with him and he was spinning and hopping around like normal )
