Oh, the brown one looks just like an amber link I had. I'll stick with my original feelings. Leghorns can get big combs, females too, so wait for other characteristics like the saddle feathers growing in long and pointy.
Iam going to guess pullets on both. The white one has a bigger comb, but since she has leghorn in her, im not going to worry about. Plus, it's not terribly large.
