Duck eggs are alkaline which is very, very good for your body. They like to lay eggs in deep, private places. If you provide them a good place like that, you will be able to find their eggs and use them. If you don't they will lay where ever they find a place that feels safe. Just this week we had a broody duck hatch a chicken. LOL. So cute. The duck quacks and the chick runs to her. This should be interesting.
