I have 9 hens, 3 are bantam cochins, 1 EE, ( beautiful green eggs), 1 Polish Cross, 1 Red Sex link, and 3 barred Rock crosses. I am getting the obvious small cream colored eggs from my banties, and beautiful brown eggs from the BR Xs, but I just found a lovely egg that is lighter, it is PINK!! My polish cross came from the same yard as the Barred Rock crosses, and has some black spot on her. Is this possibly her laying these pink eggs??I was expecting white eggs from her, but I thought you genetics specialists would know.
