Is this normal?

I have a muscovy egg on day 29. The other day it was creamy white color....today when momma duck stood up I can see shading from the inside. Some little dots gathered together on the side and a dark top around the top of the egg.

IS that what happens before a hatch or the duckling died?

What color are the dots? DOes it just appear to be colorization on the egg or is it actual "goop" type of stuff?
