I got three ameraucana chickens that are 15 months old. I was told that they all lay true ameraucana blue eggs. None of them laid for about two weeks after being relocated. When they started up again, two of them lay the perfect blue eggs. The third lays a light brown almost creamy colored egg. Not sure why, but I'm going with it. My question is, what's with the weird pigment? All of them have come out with this weird "bulls eye" on the side. And before you ask, it isn't on the side that the egg was down in the nest (ex: some of the pigment got on the bedding leaving a lighter spot) Odd, isn't it? What are your thoughts?
