Hello, My Mallard Duck just turned 6 months and I realized she has been missing going places a lot and doesn't return till morning to eat some food...well, one day I saw her getting food out front so I watched her and she ran to a bush in front of my view. When I went after her to see where she's going I looked threw the bush and found her in top of Duck Eggs! I have no experience of cleaning or eating them..checking if there safe or not. We just wanted a pet lol. So I just got like 8 eggs from there and how do I clean, check if there good, and cook? Like said, I have no clue. There kind of dirty and have a few of her feathers on them. There is also NO male duck. I just put them in cold water to soak. Was that ok? Please I need answers ASAP (and is it good to put them in a carton in the fridgerator?
