It depends on how fast she can clench the eggs out, which will be at least the speed of a bullet (likely very much faster), and with the size of an egg that's a whole lot of force behind the antimatter. What do you guys think that could do if it fired into the Earth, taking the very low estimate of bullet speed?

We already calculated the power of antimatter explosions by weight of antimatter.

1kg of antimatter explodes with what, 21.5mt of force? So an average antimatter egg would likely hit with around 3 to 5mt of force. If we're talking facts here.
