I just sold an EE pullet to a friend. This pullet is solid blue and came from a barred rock mother and a blue ameraucana father. She has cheek muffs and a pea comb. Daddy is 100% ameraucana from the Gardner line. Apparently the little pullet is laying a brown egg. How is this possible? She would carry the brown egg gene from her mother and the blue egg gene from her father. Doesn't she HAVE to lay green eggs? I have been selling these EE pullets for a couple of years. I have always advertised them as being green egg layers. I sell them well before point of lay. Now I'm freaking out that I have told all these people that they are getting green egg layers when perhaps they are not. Can someone please explain to me in simple terms egg color genetics?
