Please read the advertisement carefully. I don't have answers to any extra questions. I've written everything I know. For sale: A tame female cockatiel. She never bites. If you hold her, she's fine. But if you call her, she doesn't come. She comes out, walks around, comes to you normally, and returns to her cage. She is very good. I don't know her age, nor do I know if she is suitable for breeding. She laid infertile eggs for me.
