I have 18 eggs incubating, a bunch are marans one egg in particular is not loosing any weight. It weighs the same as day 1 all others have lost 5% I am ending day 5 and beginning day 6. there have been no temp swings, I have added water to keep the humidity at 40-45 % daily. All of the eggs seem to be developing properly. Any thing I can do to help the one egg along. It is not porous at all compared to the others. It is rock solid.
