Moving the eggs too much is detrimental to them. Now that they are set. Please don't pick them up any more or change their orientation. That is crucial. Any commercial anti fungal powder is adequate. Just sprinkle very little where you can visibly see the mold and not to excess. Absolutely don't move the eggs any more. You have to be cognizant of the temps and humidity at all times and don't have the tub open for too long. The egg in the middle looks suspicious for not being healthy but all the others look like they have a shot. But you have to act quickly and the main thing is the temp and humidity.
