The Egg is right out of Bryce then duplicted and shrunk a bit and then negative boolean. I used a terrain to get the jagged edge then duplicated the top shell with intersect. The pieces are easy just take a couple of flat  2D vertical faces adjust them to look a little jagged add your texture. Voila! The drips on the inside as well as the egg white are Metaballs squashed or elongated depending on where they are.

Of course why make it yourself when you can download it (No offense to Pidjy). Reminds me I haven't done any instant poser (just add water and render) work lately...
