How can i tell if my bird is a boy or a girl?

Question
How can i tell if my indian ringneck is a boy or a girl at a young age, Or old age?

Answer
Hello Emma.
The only way to tell for sure if your bird is male or female is to either have a DNA test done or to wait and see if the bird lays eggs.  
There really isn't any way to tell the age of your bird, however.  If you got the bird from a breder, or if it has a band on it's leg, then the breeder should have paperwork on the bird.
I am sorry that I am unable to be more clear on my answer.

Good luck and God Bless.
