Freshly Hatched Duckling Help!

[Ahygre21]

I am incubating duck eggs and I had one externally pip on day 26- I know this is an early hatch. Today is day 27, and within 24 hours no progress was made and I needed to assist the hatch. I was able to get the duckling out, the yolk was absorbed. I put it back into the incubator but now it just lays on its back and its feet are shaking (kind of like tremors) Not sure what to do? Any extra nutrient I should give once I move it to the brooder?

Water with egg yolk, a pinch of sugar and a half pinch of salt will help, maybe a teaspoon of nutritional yeast.
