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.
How Many Eggs Do Mallard Ducks Nesting Lay? Mallards lay between 8-12 eggs and muscovies lay between 12-18 eggs. The egg laying process lasts for an equal number of days (it takes 12 days to lay 12 eggs). Once egg laying is complete, she will leave the male (who will wait at the water for her) and she will begin incubation on the nest fulltime.
