Both eggs had the same momentum when they reached the ground.
Both eggs eventually stopped moving, so both eventually had zero momentum.
The change from (same) to (zero) was the same for both.
So both eggs experienced the same change in momentum. It doesn't matter how the changes happened. They were equal.

Hey Alice !
Where did all that momentum go ?
It can't just disappear. Momentum is conserved. The total amount never changes. If it disappears from one place, then it had to go somewhere. Where did 2 falling eggs' worth of momentum go ?
It got transferred to the Earth !
The Earth's momentum increased by exactly the same amount as what the 2 eggs lost.
