my duck has about 12 eggs

[dylanj911]

My duck laid about 12 to 15 eggs and she is sitting on them we do have a male although im not positive their fertile some have been there for at least 16 to 18 days so idk how to ensure they will hatch without an incubator I have raised ducks from 1 day old but i have never hatched 1 i need advice i tried candling but idk how to tell what the difference is any advice greatly appreciated!!

I'd just let her sit and see what happens. Either they'll hatch or they won't. If the duck is sitting on them, you don't need an incubator - she'll do the job.
