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.
My ducks lay 1 egg per day, everyday. I think there was only one month in which they didn't lay any eggs. Ducks don't normally sit on their nest of eggs till they have a full clutch(which is approx. 12-15 eggs). One of my girls started laying not to long ago and after there was about 7 or 8 eggs i gathered them.
