Petunia is not like the other chickens. She prefers colour and beauty to squabbles over bugs and jostling for place in the pecking order. She keeps herself as separate as she can be while sharing the same coop as the rest of the flock.
Unable to hide her different interests and values, Petunia becomes a target of the other, bigger, birds. As she moves further and further from the norms of chicken society, the dangers she faces increase as quickly as her horizons.
