Death Laid an Egg (Italian: La morte ha fatto l'uovo) is a 1968 giallo/drama film directed by Giulio Questi, starring Gina Lollobrigida, Jean-Louis Trintignant and Ewa Aulin.

Plot: Married couple Anna and Marco run a hi-tech automated poultry farm, breeding boneless chickens. Unbeknownst to Anna, Marco is a serial killer, who lures prostitutes to motel rooms before stabbing them. The arrival of Anna's cousin Gabri further fragments the troubled marriage, as she and Marco begin an affair and conspire to run away together. However, Gabri is actually plotting with her husband Mondaini to kill Anna and frame Marco, as they have discovered Marco's secret. When Marco discovers Anna's body in his hotel room, he cleans the crime scene and takes the body back to the farm to dispose of it. What Gabri and Mondaini do not know is that Marco's fixation is not with killing prostitutes, but simply hiring them to role-play murders, letting them go safely and handsomely paid. At the farm, Marco falls into a machine used to grind chicken feed in which he was trying to dispose of Anna's body. When the police arrive, having responded to the "murder" at the hotel and then coming to the farm to investigate Marco's alleged activities, the police focus their attention on Gabri, suspecting her of committing the murder out of sibling jealousy. Gabri and Mondaini are eventually arrested for Anna's murder, as the farm chickens feed on Marco's ground corpse.
