There are 44 ducks (primarily female) on the farm where I have worked for six months.
I took over the feeding and egg gathering a few months ago.
The female ducks went into high gear egg-laying in early March, at which time the owners put the ducks into a large fenced area about 60 by 150 feet. They lay 25–35 eggs every day, and they lay them all over the ground — only a few lay eggs in the hutch.
On March 13th, the owners began incubating the eggs. One female duck evaded capture and has been in hiding most of the time.
