No one had me do anything. THAT would be weird. A pap is uncomfortable. A vag ultrasound is nothing. Not uncomfortable and the view will be better than a regular ultrasound.
A duck will usually lay one egg either every day or every other day.
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.
