They're actually surprisingly survivable: You get the mine the eggs until the larval core pops out, grab it quick then either jetpack ONTO, or run INTO the abandoned building. And then you wait. Repeat until you've got a full stack (or two. I've found that two stacks tend to be the easy limit.) and two stacks is worth almost a million credits.
Edit: yeah. Mine the eggs one at a time. Trust me on this. I've bought starships this way.
