Hatching Abandoned Duck Eggs?

Roughly around April 18 my sister found a duck and 13 eggs on our boat, the thing is it was getting sold. So I became the mother duck's friend and I went out everyday feeding her and slowly she began letting me pet her and she even sat on my lap. Now due to the boat getting sold my grandparents decided to get her off the boat on Sunday. So May 10 and we set up a whole new nest with shelter and everything, Benedict (the mother duck haha) needed. Everyday I've checked on the nest and she is nowhere to be seen and because the boat isn't there anymore I think she's gotten confused. So it's now 4 days later and she hasn't returned at all and only had 6 eggs left. I decided to hatch the eggs myself and I set up an incubator, but I'm unsure whether these embryos have survived without their mother for four days. Two eggs had brown/yellow liquid leaking out of the shell and I tried candling them and I see veins and a dark shadow, but no movement. So are these eggs going to hatch and survive or is it too late??
