Congratulations! How great to hatch an Egyptian.
Just a note if you're receptive - we've found perlite is a very dangerous incubation medium. Babies normally test eat everything when they first hatch (and even before with just their head out) and perlite looks like their eggshell which they normally consume entirely before emerging from their nest. However, the perlite is a volcanic glass, and will stay in the intestines creating blockage and is deadly. I know lots of folks still use it and its fine... until they have one that does eat it, and they wonder why they lost the baby several weeks later.
