I have three 1 month old baby zebra finches, but i wanted to know their s*x, their beaks are still black.?

Question

please help me...

Answer 1

If the babies are NOT white, look for the orange cheek patches.  Males will have them, females don't.

Answer 2

I have 3 one month old zebra finches too, I have 2 males and one female.  I could tell just by their colour, the males are a light brown, and the female is black and dark grey  with some white on her wings.  The boys look like the daddy and the girl looks like the mommy. :)   Hope i helped!
