This is a pullet.I’m really hoping this one is a girl, it’s turning out GORGEOUS.
And I agree. In the top-down shots, you took, judging from combs alone in the playpen I see four and four.The first one you posted is definitely a cockerel. Out of these two, the second one is definitely a pullet. It has a female specific pattern. The first one out of these two is still iffy to me. I'd say update us again on that one in a few weeks.
I believe the last (smallest - you sure that's not a sparrow? LOL) is a pullet.
