I have a few Ameraucana/Salmon Faverolles crosses & expect to see greenish/blue eggs when they start to lay; as, blue & brown makes green. This flock is just now "coming of age" for laying & most of them should lay tinted/light brown eggs. The funny thing is that the first & only hen right now to hang out in the nests showing egg laying behavior is one of the Am/Favs (as described above); the one & only egg layed has been tinted/light brown, like I would expect from the Faverolles. Of course, I must just have a "sneaky, sneaky" Faverolles hen laying her egg. They may just be playing tricks on me for their own amusement. Will post the outcome of my future findings, when I figure out what's going on out there. So, my sweet hubby (who pretends to be uninterested in chickens) suggested that I pose the question on the BYC for fun. Are blue eggs dominant? Will the blue always mix "genetically" with the color of the other parents egg color? Or, can the brown just take over?
