Is it normal for an EE egg to be completely covered with a gray coating? I thought my EEer, Blondie, laid a gray egg until today when I noticed that the gray rubbed off of the refrigerated egg (our fingers rubbed off the condensation from being in the fridge) and underneath it's very olive colored. I've heard of eggs having a chalky coating, but this was not too chalky and it completely covered the color underneath. Will this gray covering go away with time? She's only laid 2 eggs so far, and she's our first layer.
