* Duck species: Different duck species have different clutch sizes. For example, Mallards typically lay 8-12 eggs, while Wood Ducks lay 8-15.
* Age of the duck: Older ducks generally lay more eggs than younger ducks.
* Environmental conditions: Factors like food availability, weather, and predator pressure can affect the number of eggs laid and the number of ducklings that survive.
* Individual variation: Some ducks are simply more prolific than others.
On average, a duck lays 8-15 eggs per clutch.
However, not all eggs hatch successfully, and not all ducklings survive to adulthood.
Therefore, the actual number of offspring that a duck produces can be much lower than the number of eggs she lays.
