That had crossed my mind since it was close to water but why didn't he eat it?
I have an egg dump for eggs that don't hatch when I set them. I throw out huge amounts of eggs.. Raccoons, fox and coyotes eat some eggs at the dump and stash other eggs all over the place up to at least as far as 1 mile away. The fox and coyotes mostly bury the eggs with the top frequently flush with the ground. Lots of eggs are just left randomly in the open. I find lots of intact eggs within a few hundred yards, in all directions from the dump.
I'ts possible the raccoon ate its fill at the nest and then carried off the other eggs.
I should put a trail camera on my egg dump.
