Finally!! After all this time of waiting and searching for eggs, I have a duck egg!! The dog found it so we went on a search to see if we could find the nest. We found it, with another egg shell in it. Evidently the stupid dog ate one egg and brought the other one 'home' for later. But now I know where to look! I'll make sure to stop and check in the mornings when I take my son down to the bus, since I have heard they lay at night/early morning. I'm so HAPPYYYYYYYYYYYYYY!!!!!
