Found these wild duck eggs around 5/7/22 (Part 4, early morning, eggs were missing) 5/17/22

I got up and went out to check the momma duck and her eggs, momma was not there which is never happened before, and also noticed 6 eggs crack open on the grass only 3 meters away from the nests, and 4 eggs are still in the nest, I WAS HEART BROKEN, wondering what happened.....hoping for Momma back soon.....
