My Budgie has been pretty irritable for the past week, I just re-entered school (every second day for 5 hours) and I let him out from the second I get home till around 7-8pm every night. I'm not sure if he is molting, or because of the sudden change is lonely or stressed, he will be super calm and chilling then squawking and chirping (angrily) Im not sure what to do or what it even is! He's around 4 months old now and any help is appreciated!
