He does look like an EE with that color and those green legs, but he doesn't have a beard and muffs. His comb looks like a couple of my EEs combs though. Hmmm...not really sure. I would say he is an EE, but I could be wrong.
No way to tell whether he's an EE unless you are getting colored eggs from his offspring or you know what his parentage is (and I don't think you do or you wouldn't be asking!) Oh, and I have a couple of EE pullets with white ears and one with red. It has no correlation whatsoever to egg color.
