I am in Scotland so I don't think it will be a snake!? I have seen a few magpies about recently though... Could they manage to take the whole egg away? There was no sign of the shells anywhere.
My ducks go out in a run through the day and are shut in at night. They had layed 3 eggs outside this morning and when I went to shut them in tonight the eggs were all gone. What could have taken them. Thankfully the ducks seem fine, I'm worried about them now though. What could it have been?
