I am still trying to understand the blue/green gene. I got 4 chickens from a friend. i roo and three hens. One hen lay a blue egg, one lay a light green egg and the other lay a pinkish egg. Of course the roo I have no idea what color egg he came from. This year I have a bunch of dark green egg layers. If I understand the genetics behind the egg color I am going to guess he was hatched from a green egg. Two of the hens (the blue layer and the pink layer) my friend got with the roo. The third hen was the offspring of the trio. So I am guessing the roo mated with the light green layer and I got a bunch of babies that lay dark green eggs. If I take the dark green egg layers and put them with their father that will make their eggs even darker right??? (Does this make any sense to anyone???) I want to seperate everyone into breeding pens and sell egg for hatching this spring.
