This is one of my regular ones. Which I think is female because she has dark chest unlike the boys who have a white chest.

This is a pic of her wings.
I believe the two I posted above are females.

This is another one of my regular ones. I think this one is a boy because he has a white chest, his comb is a lil bigger, and his wings are very different.
