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.
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).
