I also have barred rocks, RIR & Black sexlinks. I just got the EE Roo and can't wait to start breeding to see what they will turn out like
Looks like you've got a really fun project started there.
Just some clarification, in case you didn't know, you won't be creating EE's. You will have some really pretty and fun barnyard mixes.
Your EE rooster, likely received just 1 blue egg shell gene (there are 2 possible to inherit from parents).
That means he will have a 50% chance of fathering green egg shell layers (if brown layers used) and 50% plain brown shell layers as he likely has just 1 gene. (He may have no blue egg shell genes, but he has a pea comb and enough signs of Ameraucana left that I think it is safe to assume he likely has 1 blue gene).
The feather colors will get interesting between the RIR and your roo. You should see some fun red patternings and partridging. You'll probably get black with the BSL's, but possibly some pretty red bleed throughs.
What you won't get are EE's as Easter Egger is not a breed but a hybrid already. You will be breeding hybrid to hybrid, so you will get barnyard mixes. (Fun and interesting birds).
The more you breed away from the original Ameraucana genes in the original EE hybrid (pure Ameraucana over any other pure breed), the more you dilute out the blue genes for coloring. You will be getting very pretty, fun, barnyard mixes with more and more likelihood of brown eggs the further you breed away from the EE.
Your EE boy and your EE girl will have a good chance to recover the blue genes as you already know she lays a blue egg...and with assumption your boy has 1 blue gene. That means, if I run the Punnett square correctly, you'll likely get 50% blue/green, 25% deeper blue/green, 25% brown or white (depending upon some other genetics that include the brown wash or not).
If you are going for egg colors, I would breed your two EE's, then keep breeding back their progeny (daughters to father) for 2 or 3 generations (not breeding those that lay brown eggs). You may recapture some solid blue layers again.
Just my thoughts,
