94 is far too hot in my opinion. I don't go above 90 ever. This year I am incubating at 88. If you mix vermiculite correctly and seal the egg box then you shouldn't need to add any water for the entire incubation period. I believe a 6qt tub is a little small for incubating. I use 18 qt tubs. More medium, more stable temps, more humidity. Good luck!
