Eggs Range in thickness/size and in color.
Ostrich eggs are quite thick, and are compared commonly to the thickness of a nickel. This can range depending on how the birds are fed, as with all eggs.
Turkey Eggs, Quail Eggs, Peacock, and some other smaller birds' eggs have a mottled or dappled design on top of the base color. This can be removed with little effort, but I prefer to keep that color and texture.
