My advice is just take a deep breath and relax if getting it done via vaginal ultrasound. Sorry if this TMI for any of you, but imagine the vaginal wand as if it were like your significant other putting himself in you.
The runner duck, the Cayuga, the blue Swedish and the buff duck are among the top layer ducks, averaging up to 180 eggs per year. Poor egg layers such as the mallard may lay as few as 60 eggs a year. Some specialized varieties such as the white layer duck can produce nearly 300 eggs a year.
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.
