I am new to this forum. Thank you so much for answering my post re the budgie. He is cute and seems to be so happy. He trembles/shakes alot is this normal? I would hate to think he is traumatized in anyway. He sings alot, I do cover him at night, didn't know I was suppose to but figured he would like privacy while he slept. Can you leave him alone if I go for a weekend? So much to learn about this little guy, I just want him to be healthy and happy.

Thanks for your help!!!
