I wonder at which point ‘where did I leave my eggs?’ becomes a greater evolutionary pressure than ‘I need to hide my eggs’, because I’m assuming cassowaries haven’t had to worry about the latter for a while!

All (chicken, at least…probably other species too) eggs start out white…but pigments get added near the end of the egg development process.

That’s how my girls have eggs in many different colors.

Same, those are crazy looking!
