Hatching eggs???

[Alayna Smith]

My Muscovy duck laid 10 eggs. They were suppose to hatch today but haven't yet but when I went out there the had moved one beside her and wasn't sitting on it. The egg looked like it had grease spots on the inside. Is this a sign of it about to hatch or what??

Possibly a bad one?....They reject eggs if they are no good ...Keep waiting ...My Call is also due today....Fingers crossed for both of us...
