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

From the moment she hatched from her egg as a cute little ball of fluff, this chicken has been told over and over again how she is a powerful alien intend upon conquering this planet. She wasn't interested in all this nonsense when she was a tiny chick, she just wanted to cuddle under her mother's warm wings and be comforted. Unfortunately, she didn't have a mother under whose wings she could cuddle, only a weirdo in a tartan skirt who tried to teach her how to peck at the buttons of various machines and questioning her what she remembers of "The Mothership" or her "Home-planet". As a result, she became a very unbalanced teenager, and later slipped into a permanent psychosis. She now fully believes she was send to this planet by a population of fowl living on a distant planet in order to prepare the way for a full-scale invasion. She has hidden herself in a cave up in the Highlands, only occasionally venturing outside to collect the nuts and bolts needed for her secret weapons.
