What are pysanky eggs used for?

Almost all bird eggs are suitable for pysanky. Non-white eggs, such as Rhea or Emu, require special techniques, but can still be used for pysanky. Chicken, Duck and Goose eggs are most commmonly used. They require no special preparation, only simple cleaning to remove dirt. Ostrich eggs have a heavy glossy outer coat with amny irregularities. They are usually sanded to a smooth finish before using. Rhea and Emu shells come in shades of dark green to light green. The light green shades can be dyed without removing the outer shell. To use the dark green shells one would have to remove the top layer by etching or sanding. Finch eggshells can be used, but they are fragile to the touch. Pigeon eggs tend to be oily and do not dye well. Parakeet shells are the best if you want to make tiny pysanky.
