The ducklings hatch with a full set of feathers and open eyes. This ensures that the ducklings will hatch at approximately the same time and that none of them will get left behind.ĭucklings use a pointed bump on the end of their bill, known as an "egg tooth," to crack open their shells. Toward the end of incubation, developing ducklings begin making a range of subtle sounds called " pipping." Remarkably, ducklings know when it's time to hatch by communicating with each other while still inside the egg. Despite differences in the ages of her eggs, which can vary by as much as 10 days or more depending on the size of the clutch, all of them typically hatch within a 12-hour period. A nesting hen lays about one egg per day until her clutch is complete, and she will incubate her eggs for about a month after the last egg is laid. Although brood ecology is not as well studied as nesting success or adult survival, we've learned that ducklings rely on a combination of camouflage, clever behavior, quality habitat, their mother's vigilant care, and a little luck to survive a multitude of dangers before fledging in mid-to-late summer.Ī duck's life story actually begins before it hatches from the egg. Research tells us that duckling survival is a close second to nesting success as the most important factor influencing the size of duck populations. One of the most crucial times in a duck's life is the period between hatching and fledging.
