Kiara and Calli Talk About Laying Eggs 

They actually come out anyway, just not fertilised, confirming it as a bird owner. So Holotori could definitely do too IMO

In the real world too.

''Kiara did you lay this egg?''

STOP PUTTING WEIRD IMAGE INTO MY HEAD KIWAWA 😂

Is it an actual egg or the metaphorical one? If its actual, all females lay eggs.
