Most likely she won't come back to nest if pred has been in it, this "dog house' is it pred safe? if so maybe build a fence around it and if you really want to have her nest there lure her in with food,. put bedding inside the house and wait, either she'll go in or she won't but if she does start laying then before she starts to sit you'll be obligated to go out each night and close up dog house to protect the eggs, then in the morning back out to open door to let her in to lay, once she has laid the amt she is happy with she'll start to sit, then you'll have the responsibility of making sure she is safe by closing her in of a night and opening door in the morning, but once you commit you'll have to stick with it for 35 days and beyond, food ,water and safety are her constant companions,. Then her and ducklings will have a fighting chance.Well I see her everyday but she won't go in the duck house pretty sure tje remaing eggs are no good ...oh well what are gonna do.
