I noticed a duck sitting on her eggs in my front yard this afternoon. House is in Chicago . I was in the middle of sprinkling PREEN weed treatment on the flowers beds. This is where the nest is... IN THE FLOWER BEDS under a bush. One egg is on the grass and broken. She will not leave and I do not know what to do about this whole thing. I did not notice that the duck or the nest was there until after I started washing the windows and making lots of water noise spraying the windows. I did not know od the nest or the duck
