Does anyone know what kinda chicks I’ve got and what sex they may be?

[GypsyGen]

My sons kindergarten class hatched some eggs and what can I say, I’m a sucker! So now I’ve got 4 6/7 week old chicks. So I need some help! Can someone tell what kind of chickens these may be and the sex?when I asked the teacher she said they were a random mix she bought from a feed store. The little black one is bantam any guesses as to the breed?

The first one is an Easter Egger pullet,
The black one looks a lot younger, I’m not sure, but may be Australorp pullet?
The third looks like a mix of something, like Barnvelder and Bielefelder, idk. But that one looks like a cockerel.
The fourth, I think, is a mix. There must be some Americana in there. Pullet, i think.

All are mixed breeds. Lot of EE DNA going on. The first two birds are your only pullets.

The first one is an Easter Egger pullet. Second looks like a serama. Third is a silver laced barnevelder mix. The last ones are cockerals.
