Richard,
What temperature were the eggs at when thrown? You might need to compare
eggs straight from the fridge with eggs warmed to ambient temperature.
Also, you might consider placing a sample of eggs in an "inverted"
orientaion for an hour or so before tossing to see if the centre of gravity
changes and affects the flight dynamics and consequent landing/shock
characteristics!!!
