Yep, that oughta work.My son wants,to try his hand at getting some olive eggers in his flock. We have had chickens for 11 years. After looking into it, through this site, this is his plan...
He is going to pick up some eggs on Sunday from an NPIP breeder that are true Ameraucanas laying blue eggs. He'll put those in the incubator and has ordered Cuckoo Marans chicks to be picked up the same time that these should hatch.
The cuckoo Marans don't lay as dark of an egg, but should be dark enough. The BCM are very hard to find right now. Even hatching eggs. Also, the Cockoo Marans should be sexlinked because the barring pattern will only go to the males when you have a non barred rooster over a barred hen.
How does that sound? Is that a good plan?
Some cucko marans can lay dark...some are real light...you'll just have to wait and see what you've got.
I just picked up some BCM eggs local.....can't find real Am's around here tho.
