Because we do not know the friction a duck surface has. It is
probably higher than a human's (due to the feathers).

I do not think they would be squished by air pressure. That's
because the high density air would also fill their lungs from the
inside which would counteract the pressure from the outside.
Which is why fishes are not squished even thousands of meters
below the surface and why deep sea divers have to add pressure
as they go down.

I don't think so. It depends on how dense the material is, i.e. how
many air bubbles are enclosed. A diamond would not be squished.

To sum it up:
Hole only to the center of the earth: duck would crash
Hole all the way to the other side: duck would yoyo eternally
Hole only to the center of the earth: duck would burn, then crash
Hole all the way to the other side: duck would yoyo several times
and finally stop at the center of the earth (quite burned up, of course)

I will inform Australia you are coming.
