I've had a duck sitting on a nest for 2-3 weeks. Yesterday I went out, and she was off the nest playing mother with my other duck's ducklings. There were flies all over the eggs, but none appeared broken. She never went back to them all day, and today I see she has covered them all with shavings so you can't see them, and is playing nanny to the other ducklings again. It's been very warm here, so I know the eggs have stayed warm. Should I leave them be covered up like that, or should I remove them. I guess I could candle them and see if they are viable, but I don't have an incubator and really didn't want to do that, I was just going to let mother nature take her course with the eggs and ducklings. I have 9 adorable ones now, and more on the way.......if nothing goes wrong. I really didn't want too many ducklings, so I won't be upset if they aren't viable. I hope I don't sound cold or harsh in my let nature take it's course feeling! Should I let them be or remove them? Thank you!!
