Goose egg in rain water

[Gerby26]

Its about 30-40 degrees F where I am and we have gotten rain/snow in the past 24 hours, I noticed a goose egg right next to my house(my girls love to lay here) it must of been laid within the last 24 hours because it wasn't there yesterday morning. But my house drips on the spot they like laying their eggs, is this goose egg still safe to eat or should I toss it.

Toss it if it's sitting in water.
Mine sometimes lay in the mud
