Help sexing

[mom-to-5]

I have three chicks that are 4 weeks old. They are barnyard mixes from my splash silkie roo, so all have a pea comb, 5 toes, etc.
The first one is from my blue Andalusian hen and the other two are from my NN hen that went broody and raised these three.
First one I'm guessing is a pullet

The second one is the lighter Of the two NN's, I'm not sure but leaning towards roo due to comb and wattle development starting

And I'm guessing this may be a male also

Lastly, a pic of all of them to compare...

Opinions please...and thank you!!!

The first one I think is a pullet the second one I'm leaning towards cockerel but I'm not positive on the last one.

The last two look like cockerels to me.

Thank you all, this confirms my guesses. I was hoping one of those cute, black skinned NN's would be a hen but I may be keeping another rooster if not.
