And the reason they do it this way is because if you remove the eggs they just lay more.
The same things works for pigeons by the way. You get them to lay in a special nest where you simply make sure they don't hatch.
Though in this example they simply shake the eggs, which is apparently enough to prevent them hatching.

This works with most birds apparently. Take the eggs away, they lay more.
It's really helped bring back the falcons in NY.
