I am wondering how long she was off the nest? Or are you starting with new eggs? My tried and true hen, on day 17 got on the wrong nest. And they must have gotten too cold, as none of them were any good
So if she has been moving those eggs may not be a go, but if they don't, you can always slip chicks under her in the dark of night. You might be looking to see if you can get chicks somewhere around the 21 days, or you can add chicks to your clutch if you want a different breed. Perhaps you know all this, sorry.
However, having a broody hen do the work is the best. It is cold and rainy here today, and she has them tucked up under her as warm as toast. Mine stay with the flock, and mama must be tough, or perhaps it is my roo, although I have never seen him do anything, cause no one bothers them at all!
