Cardassian egg painting

I know it doesn't make a lot of sense for Cardassians to lay eggs but humor me for a second here because imagine the culture that could evolve around it.

You know how reptile eggs shouldn't be rotated during incubation otherwise the baby will die, so breeders will often mark the top of an egg so they know the proper orientation? What if Cardassians do this too. And what if it's evolved from simple markings to, like, auspicious sigils. Like, you can wish your baby health/prosperity/filial piety/etc. by painting or stamping the corresponding symbol on top of their egg. Of course it's superstition that this actually affects the baby's fate, but even non-superstitious people do it anyway, just because it's tradition.

The substance that the symbol is painted with also supposedly affects the baby. This is a bit more scientifically sound, since chemicals can penetrate the shell and influence the fetus's development. Traditionally you'd use different kinds of herbal dye, but in modern times people are getting more scientific about it and using dyes imbued with chemicals that are proven to be beneficial to fetal development.

There are established symbols that signify different well-wishes, but of course people get creative with it. You can incorporate multiple symbols in your design, or hire a fortune teller to come up with a personalized design for your baby, or just add your own little flourishes. The designs can get quite elaborate. In modern times, parents who don't believe in the superstition of it have started painting other things on their eggs. A pretty design incorporating the baby's name, writing a letter to their baby, drawings with sentimental but not spiritual importance.

If the baby hatches in a way that doesn't damage the design, parents will often preserve the portion of the shell that has the design on it as a keepsake. If the baby does damage the design when they hatch, it's considered a bad omen, and a sign that the baby's fate will be the opposite of whatever the design symbolized.

When you walk into a Cardassian hospital's incubator room, you'll see eggs with all sorts of different designs—and some unmarked eggs, too. Those are probably orphans or bastards, babies without parents who care enough to wish them well. Sometimes hospitals will stamp those eggs with a generic, simple design wishing health. Usually not, though.

very enjoyable!
