Those
may well both be possibilities, separately or in combination, as are other
scenarios (like starvation or just unhealthy). I have had a similar incident
with them nesting in my tree. But I don't recall whether there was any bad
weather involved.

The resident currawongs have raised another chick to
fledging in a eucalyptus in my backyard. That makes two this season. However,
after the heavy rains of early last week I found a dead chick under the nest. It
was about half feathered and got me to wondering if it had died on the nest from
the cold and wet or had been evicted by the its now-flourishing sibling. My
meagre references are silent in this regard.
