how can u tell if a parakeet is a boy or a girl?

  the fleshy part around the beak where the nostrils are. Boys' are usually blue or purple.



The girls' are usually brown, cream or yellow.
You can tell the sex of your parakeet by the top beak color. If it is blue its a boy and if its pink its a girl. It is hard to tell when they are young but the color will eventually show.
Flip it over.
color above their beak
