Is one of these a cockerel or both pullets?

I have two opal legbars I'm wondering if both are pullets or if one is a roo because they look so different. One has longer tail feathers and minimal barring. The other has a large crest and lots of barring. ???

How old are they? At this point, both look like pullets.

They're 6 weeks old. Why would they look so different if both are pullets?

Sometimes chicks feather out at different rates, and even within a breed there could be variation depending on the quality/source of the breeding flock. Both do look to be pullets.
