I brought the egg into the house and it measures the size of a quarter. It is so cute. My chickens are white orps, black australorps, turkens, new hampshire reds and a few other standard sized chickens. I have 2 hens that consistently lays eggs that are as big as a duck egg even almost as big as a goose egg and those eggs are always double yolked eggs. I sure hope the hen that layed this little egg starts laying bigger eggs. I wish I had a camera to take a picture of the egg for you to see. I don't want to crack the egg open.
