I have been observing the tails of the young male and female peafowl and have come to the conclusion that there is a difference in at an early age, makeing it possible to tell the white males and females apart at an early age without DNA.
However if you are wanting to know when they hatch you will just have to pay to find out.
here is my pied pair, this is the first time i have ever seen the femal fan and as luck would have it i caught the male pied fanning next to her.
The females on the left and male on the right, notice the difference in the tail feathers.

This is a white female with 2 males.

this male was 7 months old in this photo.

I saw all 12 of mine fanning at the same time at the pond yesterday and all the females had rounded tails unlike the males which had longer feathers in the center of their tail, i remember Clinton posted males had more tail feathers that females so mabe this is what we are seeing here.
