I was just wondering that myself...out of my 7 EE's 5 lay green, 1 lays blue and one brown. My blue layer is molting and I got a blue egg today. My understanding is they don't lay when they molt?
This is their first day out of the coop, they were pretty snoopy when I left the door open. I hope my hens lay eggs almost as large as yours. That one was huge!
