This is my second year of owning hens, and my EE's are still outperforming my Buff Orphington, Black Australorp, and Light Brahma. My EE's, Archaeopteryx and Salem, lay a blue egg and cream egg, and both are always the biggest at around 65 g. or higher. The BO lays close to that size sometimes, but her eggs are uh, "special" (usually torpedo shaped and the last one was flattened!) but infrequently. The BA lays about 60 g. eggs but not as often as the EE's, and the LB lays as often as the EE's, but she lays the smallest eggs! (and she's of course the biggest of the lot too!) Today was a five egg day so I got a pic of all the eggs.
By the way, some time back I saw mention of breeding RIR to EE's to make olive eggers...That won't work so much. Sure, you'll get olive-ish eggs, but more in a murky kind of way. The way the best olive eggs come about is by breeding excellent blue color to copper marans that have as dark a color egg as possible, since they'll be lightened up by crossing with as light an egg color as blue anyway. Depending on how dark a brown your RIR lays, you might just end up with a muddyish brown egg.
By the way, my one EE is proof that while the blue egg gene and the pea comb are really close so they nearly always travel together, there IS a bit of drift (15% I think?) which is why every now and again you get an EE with muffs, beard, and pea comb but they lay a cream colored egg like my Salem. (or why you end up with a beardless straight comb hen that lays blue eggs)
