Someone was trying to make a joke.

The Golgi complex is an intracellular structure involved mostly in
packaging material in the cell into vesicles for transport within the
cell or to the outside.

The brain of a chicken is no great shakes compared to that of a
mammal. Still it is an elaborate structure with forebrain, midbrain,
and hindbrain, all composed of many specific brain centers, each
center containing millions of cells.   (And each cell has a Golgi
complex).  The brain is a lot larger and more complex than, say, the
brain of a frog or a fish or of most invertebrates.  I don't believe
it is really significantly different in magnitude or capability from
that of any other bird. (But, then, being called a "birdbrain" is no
great compliment!)
