Beautiful Eggs!!

Is anyone else as fascinated as I am with the absolute beauty of the eggs our girls lay? I've got white speckled eggs, purple speckled eggs, mauve eggs, golden eggs, brown eggs, big eggs, small eggs, swirled eggs, pixel eggs. Oh, and the beautiful textures!! I just wish I knew which one of my hens layed which egg, I never seem to catch them in the act. Does a hen always lay the same exact color/texture, or does it vary lay by lay?
