I agree your rooster looks like Marans, I think they say that is the model for the old rooster picture on cornflakes...if not that breed, then the cornflakes model rooster.
If one of your barred (black and white) is an EE, then it is the one with the small comb -- if they are the same age....I guess that would mean a barred daddy and an EE mother. The other B&W looks like barred plymouth rock. The last one, I vote Leghorn too, or a leghorn cross, the rest, especially the white one in the second to last--EE. (except the one people are saying looks like American game hen I agree). I guess if you get green or blue eggs---you know for sure EE.
