Wilton may soon have to “make way for ducklings,” as a mallard hen has made a nest in Wilton Center near Subway. Signs warn against disturbing the nest, which has eight or so eggs in it. Hens lay more than half their body weight in eggs and thus require a feeding and resting area that is free from predators. It is not unusual for ducks to lay their eggs in urban areas, and have been known to favor roof gardens, courtyards and flower boxes on window ledges, the latter making it difficult for the ducklings to leave safely. She will incubate her eggs for 27 to 28 days until they hatch. According to National Geographic, mallards are thought to be the most abundant duck on Earth. — Susan Shultz photos
