Easter eggers are not a specific breed.
They are not a group of breeds.
They are a hybrid.
I am choosing to cross a ccl with a brown egger because it will give many many eggs and yes green eggs.
I have done this experiment of course and many friends of mine who sell easter eggers have done it.
It is not the best way to create a blueish or greenish egg colour.
It is the best way to create an egg laying machine that lays an amount of her eggs in easter egger colorations.
I crossed a geeno duke hybrid rooster I bought with columbine skyline hybrid hens I bought and I created this machine. And if I had the chance to have my own legbars I would do the experiment with red sex links as the d stock. I think it would work perfect.
I would actually argue that EEs are more of a landrace than a hybrid. They are not a mix between two different breeds like a hybrid is. Instead they are a distinct group of birds that share common genes but in different combinations. They are genetically diverse but share common ancestry.
I really do thing crossing production white leghorns to EEs, then breeding the F1 birds back to EEs is your best best. The white egg color will also lighten your eggs a bit and make them prettier.
