I currently have a cockatiel and I've had him for a week now. From what we've been told he's a month and a half old. He's currently going through weaning as we are handfeeding him but there's something that bothers me. He keeps screaming. After being hand fed he continues to scream. If he is left alone in his cage he climbs up and down in an urge to be let out and chirps instead of screaming. But once the door is open he will fly to me and continue to scream. I bring him with me to do computerwork, thinking he will eventually calm down, but he continues to scream. Even goes as far as getting of my shoulder onto my keyboard to get my attention. (As I was typing this he did so aswell) If he's not hungry , and lack of attention isn't the problem. What is?
