Hello, helpful friends! 
Was wondering your opinion on my duck eggs' coloring. They are towards the end, haven't changed in a few days (possibly drawing back before hatching), and are turning a kind of gray shade in a few small places (not the air sac). OPINIONS?
Thanks in advance.

 When are they due to hatch? Were they shipped? If they were shipped there is a higher probability of them being malpositioned inside, which can cause them to try to pip in areas outside of the air cell (which can cause a dark spot to appear on the egg shell).
