PM Popcornbird, she's been a cockatiel mom for a long time! She's not online as much now that she has a human baby, dear little M, to take care of, but I bet she'll help you!

Be prepared to have a large enough cage for he or she to be able to move about, perches, and read some of the previous Pets of the Day who have been cockatiels stories, that'd be a start!
