I don't have a lot of experience with EE's, so take it this with a grain of salt, but I'm thinking cockerel, too. It's comb is small but it is way redder than my Ameraucana girls that are close to the same age. I think white is more common with males than with female EE's, too. Have you thought of posting in the EE thread? There are some very experienced people there, too.
Stang, that little cockerel is so cute. He looks splash, but that's not possible, is it? You have black over splash, right? My kids have been begging me for a frizzle.
I need to find a good home for the Blue Wheaten Ameraucana. He's my avatar right now and is just starting to get his adult feathers. They are coming in blue with mahogany lacing and it is beautiful.
