I have seen film of the same behaviour of a captive bird but I think at
the Alice Springs zoo or whatever it is called. Rather than use real
eggs, it is performed with a fake egg and after breaking it, there was a
dead mouse or something similar inside.

Part of the Healesville Sanctuary (in Victoria) raptor flight display
which
I saw in April 2009 included a demonstration of a Black-breasted Buzzard
breaking eggs with stones. We were assured that this was a natural habit
of
the species, not something taught whilst in captivity. I was so
gob-smacked
that though that was only 16 months ago I can't quite remember precisely
how
it was done! IF I recall correctly, the bird held a large stone/small
rock
in its bill which it then hurled at the egg from a standing or jumping
position. If it missed or the egg was only cracked, not broken, it
collected
the rock and had a second or third attempt!
