I think Mrs. Quackers has moved out. Yesterday, when I got home, there was an egg out of the nest and broken open. It was filling with ants and I told E we should get rid of it before it started to stink. We didn't want to scare Mrs. Quackers so we waited. This morning, she was not in her nest and there were 2 or 3 more eggs shoved out of the nest and broken open. E went out, got rid of the shells (which were now empty and not yolky anymore), filled up her little dish with some more cracked corn (we think she was nibbling at it some) and watered the shrubs (which is hard to do when you have a duck sitting in them). He saw her waddling back to the nest when he left for work. When I got home this afternoon, she was not in the nest but it was covered as we have seen it before so I just figured she was out for lunch (or wherever she goes). It is 4 hours later and she has not returned. Also I noticed some of the mulch is dug up and scattered around. I don't know if she came back and noticed the shells missing and smelled our scent and has now abandoned her nest. I hope not. I will be very sad if Mrs. Quackers does not come back. I will be very sad if we don't get to see some cute little ducklings in our yard.
