When everyone is completed interpreting the shapes, the egg yolks are used for baking “dumb cakes,” As a result, the fortune-telling is done in silence. The Scottish variant of this fortune-telling technique is called “drop glasses.” A group of ladies gets together, and everyone brings an egg and arms it to the lady in cost. In England, such eggs are historically called “wind eggs,” from the perception that the bird laying them has been impregnated not by the rooster but by the wind. This perception is probably going derived from the truth that the bodies of aged roosters (seven years or older) are often found to contain a white egg-shaped globule. Many cultures consider unusual eggs–misshapen, empty, yolkless, shell-much less, or ones with the yolk and white merged–to be laid not by hens but by roosters.
