Condensation is going to form inside the egg tubs. Its really nothing to worry about as long as its not dripping on the eggs.
I hatched two clutches last year. Hatchrite,light diffuser panel, a little extra water,press and seal and a snap on lid. There is one small(1/8'')hole in one end of the tub. I keep it covered with tape for the first 6 weeks.
Condensation formed on the press and seal as well as the sides of the tubs. No mold grew.All the eggs hatched out healthy babies.
