They don't. They follow SOMETHING (almost always the mother hen)
and "imprint" on it. This was illustrated rather strikingly by
naturalist Konrad Lorenz who had incubator-hatched baby goslings
imprint on him:
"Lorenz demonstrated how incubator-hatched geese would imprint
on the first suitable moving stimulus they saw within what he
called a "critical period" between 13–16 hours shortly after
hatching. For example, the goslings would imprint on Lorenz
himself (to be more specific, on his wading boots), and he is
often depicted being followed by a gaggle of geese who had
imprinted on him."
