Black Australorp and Midnight Mystic Maran Chicks... which is which?

[KrupkaChickens]

I got chicks the other day and didn't realize how similar these breeds look as chicks. I know they will look different when they are older but I'm curious if you all can tell which is which right now. One has black legs and a little more white on the top of it's head!

The one on right side picture is the Australorp.
