Well, the chick grew up into a chicken, but you’re still not sure how the egg got into that cave...

Chucken's mother was born nearsighted and deaf, and one night she stumbled away from her coop. Unable to see in the dark, she wandered until she came upon the DragCave. There she hid among the dragon's eggs, and she lived in peace, feeding upon grains on the floor. She laid Chucken's egg, as well as a few others, before wandering off again. Chucken grew up to be a strong, healthy chick after being stolen away from the cave, and went to chick school. After graduating as a valedictorian and at the top of her class, she went on to college to earn her bachelor's degree in politics. She later went on to become a senator, and is currently running for president in the elections. She funds her campaign by selling chicken wings. One can only wonder where she gets them.
