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 total number of eggs that a female can lay in one nesting attempt varies widely depending on the species. For example, many tropical birds lay clutches of only 2 or 3 eggs. Waterfowl, such as Wood Ducks, can lay up to 15 eggs in one nesting attempt.
