Gender Determination?

[Cebby75]

Hello guys got a quick question - What are the easiest ways to determine your pacmans gender?
I know males have the beards, what age would you expect to see them develop?
They also sing, haven't heard any of that...
Also I've heard there's differences between the male and female snouts, anyone know what I should look for on that?
I'm hoping it's a girl

Males will be smaller than females. 2 1/2 - 3 1/4 or so inches STV in most cases. Also males have nuptial pads on the thumbs
