How to tell gender and breed in baby chickens?

What is the best way to tell gender? breed?

I have no idea what these babies are. They are around 1 week old.

Unless they are set up genetically for sex link sexing, there is no real way for us amateurs to do it that young. At about five weeks some differences start to show up.
