I don't see anything that looks even remotely like an Easter Egger. You say you know they are mutts, but you want us to tell you the breed.... Mutts are mixed breed chickens, so that's what they are. Not trying to be rude or mean, just trying to explain.
That said, the red one could be a RIR cross. The buff one with black in her hackles looks more like a Buff Sussex. Do you have those there?
