help with breed of chickens

[NCChickie]

I ordered a mixed flock - some are very obvious as to their breed but due to having lost a couple of chicks in transit, I can't pair these up and I'm having troubleing identifying them. I beleive the first one with the arrow next to it is a speckled sussex (head shot in the corner) and the other maybe a marans. They were hatched feb 24th which makes them about 8 weeks old in these photos. Sorry I couldn't get the first one to load the right way Thanks in advance for your help.
