Any Idea what breeds my chcks are?

[The Coreys Coop]

Here is a couple pictures of my chicks. I have 4 total. One of my pictures is a single chick, any idea what sex and what breed it is.
One of my pictures is a picture of the three other chicks, what breed do you think they are, and possible sex?
Thanks

The top one is a silver laced wyandotte, and is a rooster.

I'm not sure about the others, but I think the one on the far right is a welsummer, and I think it's a girl. The black one in the middle looks like a girl, but I'm not sure what breed. The white one on the far left looks like a cockerel, but I'm not sure what breed.

My guesses on the last pic are: splash orpington, black australorp, speckled sussex

I could be completely wrong though!

On the right it looks like a Old English Game Bantam
