Well, my "guess" is that #1 is a roo. It has thicker legs, wadles are forming and the feather pattern makes me think roo. Pullets tend to have the same feathering all around, even on their back feathers. ANd our one roo(that we thought was a girl for 9 months(GLW), was the nicest, cuddliest bird...
How old are they? You can try to feather sex them, but I think they have to be pretty young-a day or 2 old. If the wing feathers are different sized (primary feathers smaller than coverts) girl, same size = boy. I'd see how they are in a few weeks too.
