I hope that you all can help. I have a male and female Mallard ducks. She just started to lay her first eggs. She will not sit on them so I have gotten an incubator at the request of my children. They have been in there for 3 days. How do I tell if they are viable or not? I need pictures if at all possible. I know its early but I have candled them and see nothing. Please help me out. I am considered Super Mom to my kids and I have a feeling that my title is in jeporady if I can't grow ducks.
