Chicken Egg 17
Songster
The bird in question will lay green eggs IF she inherited the blue gene from mom. There is no guarantee on that, she could have inherited the blue gene or brown gene from her. The blue gene is closely related to the pea comb gene which is why I asked which kind of comb she has. If it is a pea comb then she likely inherited the blue gene, if a single comb then likely the brown gene.
I have breed my EE with a single combed hen with the brown gene and his daughters have single comb and they lay green eggs
