"There wasn’t enough light, and besides, the side of its beak was covered with gore, so she couldn’t tell if it had the dark spot. But she didn’t need to see it.
‘Dear spirits, help me,’ she prayed under her breath.
The bird let out a slow chicken cackle. It sounded like a chicken, but in her heart she knew it wasn’t. In that instant, she completely understood the concept of a chicken that was not a chicken. This looked like a chicken, like most of the Mud People’s chickens. But this was no chicken.
This was evil manifest."
