I've only hatched Turkey eggs with my Guinea eggs so far, and all went well... I have no idea about duck eggs at all, but if it were me, I would definitely try to incubate which ever eggs use the closest temp and Humidity together, so the other eggs won't suffer or die from imperfect conditions.
I know GuineaLady93 has hatched quite a few duck eggs with her Guinea eggs in her GQF Genesis Hovabator 1588, so hopefully she will chime in on ho well they did and maybe she has some tips.
