Your question relates I think to the breeding code used in the COG
system of "cf", as in carrying food. It is a fair question, as in this
case. Maybe it just wasn't ready to eat that mulberry at the time it
wished to leave that tree. Sometimes birds carry food for reasons apart
from to feed young, although apart from in raptors, it is not that
common.
The other thing is that adult cuckoos sometimes do feed young cuckoos
that were not raised by them. I'm not suggesting this has happened in
this case. They can be stimulated to stuff food into a big beak just as
many other birds can be, regardless of who performed the main role of
foster parent.

I just saw a male koel fly out of my neighbour's mulberry tree with a
mulberry in its beak. If it parasitises other bird's nests and leaves
its young to be fed by them why would it carry food off?
