I was getting 15 duck eggs a day until 3 days ago when they slowed down to 5-6 a day. My husband had been collecting the eggs for me. I ask him if he was checking the nest good and he swore he was. When I went out to let them all out of their house I deceided to gather the eggs myself. There was only 6 laying around on the floor all were runner eggs and very dirty. I decided to check behind the bales of straw that I had made them a nest in and saw something white showing. I had found another egg but when I started scratching the straw out I found another and another and another. I kept digging and ended up with19 eggs in the nest. They had scratched all the straw out down to the dirt and would lay their egg and cover it back up. They refuse to lay on the clean straw or in nest boxes. I'm getting all these eggs and can't give them away so I'll just boil them and feed them back to them.
