Why is it automatically assumed that protoceratops was a herbivore? Surely the
old days of the
theropod=carnivore / non-theropod=herbivore dichotomy are long behind us. I
don't see any
reason to discount omnivory amongst ceratopsians in general (even if most
scavenged rather than actively taken down).
The idea that dromaeosaurs were hypercarnivores is surely also an assumption.
They may of just
as well had a broader diet similar to extant canids, for which plant matter can
form a considerable
part of the diet. It doesn't take any obvious dental specialisations to swallow
the occasional bit of
fruit or fungus.

Nest robbing comes to mind. A Velociraptor caught in the act might earn the ire
of the egg layer.
Killing and eating the intruder might just be a beneficial biproduct of nest
