duck eggs losing moisture.....and?

[ducklover101202]

I know that duck eggs lose 15% of their moisture during incubation. Can you feel that the egg is lighter when you pick it up? Or should the egg feel heavier by the hand. My eggs feel lighter all of a sudden and they felt lighter since day 15 and today is day 17. Should the eggs feel lighter by the hand or is this a bad sign?
