Mother Duck Attacked... I Need Help!!!

[yulight]

A mother duck made her nest in the front yard of my house, everything was going well until a raccoon attacked and drove away. I took the nest, I got an incubator, I thought that the mother duck had died ... but surprise, the mother duck was back after three days, I return the nest triying she incubate their eggs, but she just did not, the eggs are still in the incubator, two ducks seem to hatch... my question is how to have the mother duck accept their newborn ducklings?
What can I do to feed them?

Thank you for your experiences and answers!!!
