As I am almost positive I said before, as the eggs were being refridgerated, were they fertilised (which I am sure they are) they would not develop.
Also, the eggs may be like seeds, or the eggs of other aquatic animals in that they only develop when they are in the water, or else have already developed, and will only hatch when they come into contact with the water.
