Most female ducks begin to lay eggs at around six to seven months of age. Egg production also depends on a number of other factors.
The breed of duck can affect the age when the duck lays her eggs. For example, Pekin ducks begin to lay eggs at around five to six months of age, which is an entire month sooner than most other ducks. Lighting also can play a part on when and how often ducks lay their eggs. More consistent lighting for a period of 15 hours a day can help ducks achieve a better egg production schedule.
