Hey guys. I was just wondering, i have just purchased a beautiful little blue budgie recently but he is about 2 years old they told me. Is it possible to teach him to talk? ive read that they have to only be exposed to human talk if they are to learn, that exposign them to other birds means they will never learn the human language???.....can anyone help me out on this one? i would love ot teach him to talk. cheers
