Help Mallard eggs day 32 and no hatching

[Norak]

I rescued some Mallard duck eggs and they are at day 32 and not one of them are hatching. I have them in a incubator I got from Amazon. I candle them and see some movements but no progress. I don’t know what to do with them. I’m afraid if I don’t help them some how they they will die.
