Eggs disappearing

[Pearland]

We have a Muscovy duck who has laid eggs in our backyard. We live on a manmade lake. The way I found out eggs had been laid was one was broken in the grass. When I discovered the eggs, there were two clutches. One was being sat on. The other was not. There were 8 'extra' eggs. The next morning I found another cracked open shell in our pool, leaving 6. Those six eggs have been disappearing one by one over the period of the last month. I have found no more egg shells.

Are there marauders? Don't know why they would maraud over that period of time! Or is mama duck eating them? Just curious

Crows or Ravens perhaps?

Well depending on your location, and if there is open access from the pond to the property there could be a long list of possibilities....like reptiles, turtles, racoons, and a number of other birds....I would look for 'Tracks or Slides' around the area in the attempts to identify the route of access...from ground, water, or air....if nothing is seen then, the question has to be answered if there is a 'Dispute' between hens....one may be rolling another's egg out of the nest as a sign of 'Establishing Pecking Order'.....hope that gives some direction for you to resolve your 'Mystery'....Good Luck!!
