One of these is not like the other!

I ordered a Blue Rock with my order(hatched April 1st)
I ordered a mixed box
(4 RIR, 1 BO, and 1 Blue Rock)
My "bonus chick" was supposed to be 1 of something I ordered.
Each breed should have been easily identified.
We assumed the extra chick was also a similar "Blue Rock".
Now,...I'm pretty sure we have 1 Australorp!
Awesome! No complaints, but I want to be sure.
I am a total newbie and want to be educated on breeds.
Any thoughts? confirmation?
Here are some pics of the 2 birds. They are 13 weeks now.
p.s. the one in question has a deformed/scarred comb(injury that is now healed)

It certainly does look like an australorp. I have one named Rocky (she's a girl, named by a 4 year old). Australorps are really great, super friendly and really pretty. Right now, mine is raising 4 little chicks that she adopted. She's a great mom, super gentle and protective. She has a great personality too. I really love her.
