I have two EE hens that lack muffs or beards. One lays a gold-tone egg the other a light blue egg. And just to make it more interesting one of my muffed Easter Eggers lays a pink egg, while another lays a blue that is so pale it is almost and sometimes completely white.
I've read that the blue egg gene and muffs/beards go hand in hand, but as with the red shoulder=cockerel* myth, with EE's at least in the end it's the chicken that decides!
*Three of my promiscuously laying hens had/have red shoulders.
