After some frustration on Gleba from trying to seed recipes and manually scouring for new eggs, after a few hours did I realize that these recipes actually don't care about the input's freshness.

To save you from such an experience, I've marked these recipes down with special notation.
Note: I have no idea how to change the Pentapod egg recipe name, since I'm very new to Factorio modding. If this bothers you enough, please let me know how-to in the Discussions. Otherwise, have fun on Gleba! Knowing this is enough to make Gleba quite fun for me, so I'm hoping this does for you too.
