Were the F1 Olive Eggers bred back to Marans? Were true Ameraucanas used or Easter Eggers?Is it possible because they are F2 to have the single comb and puffy cheeks? And still be this cross of breeds?
Still possible but I some of the offspring should sport pea combs as it is dominant to the single comb. Also statistically half of the offspring would have the blue egg gene and half wouldn’t.
