Colossus Chicken of Gigantus

The Colossus Chicken of Gigantus was the archenemy of Doctor Why. As her name implied, she was a colossal hen-like alien being originating on the planet Gigantus. She once laid a man-sized egg which rolled into the TARDIS, though Why was able to dispose of it without it proving in any way dangerous. (NOTVALID: Hallo My Dalek)
