LIDERC

[Folklore] In Hungarian folklore, the Liderc is a devil equivalent to the incubus for a man or succubus for a woman. It hatches from the first egg of a black hen placed under the armpit. It carries out tasks such as finding treasure, but eventually grows bothersome because it demands work constantly and is always looking ahead to its next task. It can assume the form of a chicken or human being, but one leg always has a goose's foot. To get rid of him, one must set him on impossible tasks so he quits or dies in rage.
