Good old 'boy or girl?'

[Zapados]

One Blue Andalusian and two leghorns about 17-18 weeks old

I'm guessing 2 girls and one rooster!

All girls

All girls

I hope so

All pullets.

The brown ones have female specific coloring. They are 100% females without a doubt. I think the blue one is a female as well because of her even coloring. Both Andalusians and Leghorns have large combs, even in the females, so that may be why they look a little suspicious.

Judging by my California Whites, I'd expect a LOT more comb from cockerels at that age and I'd also expect clearly-visible male saddles.

I think you've got 3 Point-of-Lay pullets.
