Hatcher

I use a still air LG for one of my hatchers. You just have to make sure the temp is higher in a still air then in a forced air.

101-102 at egg height for a still air.

Once the conditions inside a still air incubator are stable, it's not too hard to keep them there. With the exception of changes in ambient conditions, there are no major factors influencing the internal temp and humidity.

In a hatcher, the eggs are in their last three days. The embryos are large, moving, and generate significant amounts of heat. Once they pip they also add to the humidity (often no bad thing).

The excess heat isn't very easy for most cheaper incubators to deal with, and there is a danger they could get too warm.

If I were using a hatcher like this, I would probably start day 18 with the temperature set 1F lower than the incubator, and keep a very close eye on it.

Other than that, it should be fine

I would let the chicken eggs hatch where they are, then move the duck eggs back into the fan-assisted (and cleaned) incubator on day 25.
