Easter Eggers are basically mutts, derived from a cross of any chicken with an Araucana chicken, though some people are trying to develop them into a recognized breed. Araucanas lay blue/green eggs, and come from South America originally. EEs are generally a bit for hardy with less genetic anomalies, but their egg color can be unpredictable: you don't know what color the eggs will be until they start laying. So I may get a pink, blue, green, brown or even cream colored egg from the other two. Time will tell :)
Most chickens begin laying between 16 and 24 weeks old. 30 weeks and up is very late blooming! But they come from good stock, so I am keeping the faith. At least, until thanksgiving anyways... Then we may be having chicken for dinner, lol.
