Question:
I was wondering which would weigh more: A fully developed egg about to hatch? or
One that has just been laid?
I guess I am really asking whether or not the changes within an egg when its developing make a
difference to its total mass.
Replies:
I would expect the egg is a closed system and should weigh the same throughout its development...
with the developing embryo taking its weight gain from the nourishment within the egg.
