My neighbor had a mother mallard sitting on eggs under a mugo pine on their front lawn for the last 3-4 weeks. The last 2 nights 2-3 broken eggs have been found on the driveway close to the nest.... something is attacking the eggs? There are 3 eggs left and no sign of mother mallard. The male and female mallard were around for most of April and May eating on everyone's lawn. I think they like the corn gluten being spread as a natural fertilizer! Father mallard has not been seen for some time! I will check the nest in the morning but I suspect its abandoned. Cheers Terry
