Pink either means a young budgie, or a mature male that is an ino (lutino/albino), heavy pied (clear pied), or possibly a recessive pied... Pink NEVER means female uless it's only a chick! People often times think blue means boy, pink means girl... but that's not the case in budgies! Think about eclectus, we once thought that the males and females were separate species!!!
Saying that blue means boy and pink means girl yet further destroys any possible budgie owners from being able to visually sex their birds, because as females mature, they normally obtain a white cere, with varient amounts of blue on it, then as they mature, their cere gradually changes to a tan or brown color, then normally to a crusty brown...
This thread ought to explain and show examples of what I mean...
