Thanks for all the help! I'll be posting pictures of individual chicks soon (well singles of the believed-to-be-Roos) and just one picture of the pullets... somehow Mama hatched 11 of the little things
Would it be appropriate to sell them as EEs if 50% may lay brown eggs?
No, they are not EE's, they are barred mixed birds.
Technically, an Easter Egger has no breed standard as it is a mix not a breed. It will not breed true. (The definition of breed).
It is only that first generation of Ameraucana (2 blue genes) or Araucana (2 blue genes) over some other, any other breed, that renders a first, one time, generation of the hybrid we call Easter Egger.
Taking an EE and breeding it dilutes the genes further and you've got a mix of a mix.
It is the same thing with Black Sex Links and Red Sex Links. The sex linking only occurs the first generation, so the hybrid necessary to produce the sexable chick down applies only to the first generation. Thus the hybrid name is only correctly used to the first generation. If you take a BSL or RSL and breed them, even to the same hybrid, you no longer get the characteristics of sexable down...you just get red or black mix breed birds.
So it would not be accurate nor fair to call your chicks EE's as someone will buy that, half hear what you tell them, and then sell it or breed it so that the next person has no idea how far back the blue gene may or may not be. Without very careful selection, eventually breeding EE's you will no longer have any that lay blue or green eggs.
So mark them as barred backyard mixes with the possibility that some may lay green eggs, but assure them it is likely brown eggs (to prevent disappointment) and make sure your buyers understand if they have a green/blue layer, that does not breed forward true.
