Breed guesses for 3 month olds

[kgby13]

These two are from the same batch on May 6. Hoping pullets but are they also australorp crosses?

I am unsure about breed, but the one in the first pic appears to be a cockerel. Maybe australorp or marans crosses?

First bird is a cockerel and second is a pullet. Not certain as to what the cross is.
