So I get one what I would describe as a purplish brown egg most days. Since there is only one the suspects are few in my flock of 18. So I've ruled out the 6 Bantams and the 5 Buff Orbingtons. Then there are the two BR and 2 sex links. I've had two in a day so this is not theirs. Then there are two Americanas so maybe one of them? It weighs usually 2 1/8 to 2 1/2 oz. It has a sheen on it that washes off. Which is normal but not usually seen. They are all about 9 months and older. Have any of you seen an egg color like that?
