Breed of chicks?

[Michelew650]

Just got four 7 week old chicks from my local feed store. Not sure what they are. (Except the one comet tail you can see peeking in) I posted on my local Facebook chicken page and got four separate answers. Thought I'd try here

First one is an EE. The second I can't see it's comb but I assume Sapphire Gem.

The first one is definitely an Easter Egger. The second one may be a Jersey Giant... it looks a lot like my JGs when they were that age.
