As a kid, I enjoyed reading a book called Someone is Eating the Sun
It's about some farm animals that freak out because the sun is disappearing.
They think someone is eating it, only to learn at the end of the book that it's just a solar eclipse.
It starts off with Hen who is picking at corn when she notices
the sky getting darker and she takes off with a
"flippity flap and a flutter".
Lately the chickens have been randomly taking off with
a flippity flap and a flutter
and I think about that book every time.
Only my chickens are running for no apparent reason.
