Don't know what breeds they are?

I recently got a delivery of "mixed brown egg layers" and can determine what most of them are, but not these two. Any help? (1pic of one bird, two pics of the other...). They are ~6 weeks
Thanks, Hrooster

Possibly Australorp? Black ones a cockerel, blue ones probably a pullet : )
