I've done "dry" hatching in a forced air incubator. Although it can be misleading when people read dry hatch. It doesn't necessarily mean not adding any water at all. It is just a hatching method running lower humidity throughout the initial stages of incubation and only raising it pretty high for "lockdown". For people in more humid climates this may mean they don't need to add any water during the first stages. But people in dryer climates will still likely need to add water. I ran mine between 25%-35%, and being in Texas I had to keep a dish of water in there to maintain that level. In most cases you want to be sure the humidity doesn't dip below 20%, even in a "dry" hatch.

I also dry hatch in a forced air incubator, as well as a still-air.
