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.
Others are button quail african quail and bobwhite quail which are also good layers..they lays btn one and two eggs a day. On average each quail can lay 300 eggs per year meaning each quail wouldn't lay egg on each day. However, wild quails of which some farmers are supplied by comen will rarely lay eggs.
