Recently I have begun to notice that some of our eggs have odd looking growth(?) inside of them. In the pictures below, you can see some green spots in the white of one of our eggs, and a white irregularly shaped spot on the yolks in the other photo. We do not have a rooster, so none of these eggs are fertilized. This is our second year with the same flock and I haven't had any issues until recently. Also, I have only noticed this in the blue eggs that our 3 Easter Eggers hens lay. About half of the blue eggs I crack open, regardless of age, have the green speckles. None of the eggs from our other breeds have this. So far, I have just been tossing these eggs out when I see anything that looks unusual. We collect the eggs everyday, and even when stored in the fridge, this happens. Are these eggs actually bad? Does anyone know what this is? Should I be worried that some of my hens have a disease?
