Eric was a chicken, who was terrified of his father.
Granted he was terrified, but he truly was a chicken as well, in the literal sense of the word.
He suffered years of abuse from the old rooster, and would go into the tall grass and cry a lot when no one was looking.
One day, he cracked (as opposed to hatching), and pushed his father into the oven at the bakery where he worked.
After a spell at 1000 degrees, he opened the oven door, and was horrified to discover how delicious his father smelled.
And then he ran away, because he was a big chicken.
