Death Laid an Egg (1968)
In the fragmented opening we see snapshots of modern urban life including the savage knife murder of a prostitute, committed (or so it would seem) by executive Marco. Outside the city, Marco runs a sprawling, cutting-edge chicken farm with his wife, Anna, while pretty young Gabrielle tends to their secretarial needs. Their moneyed existence produces all forms of monstrosities including a plan to bump off Anna between the adulterous Marco and Gabrielle, professional paranoia thanks to the suspicious activity of the plant’s advertising head, debauched dinner parties, and an automated factory nightmare that results in pulsating, David Lynchian chickens without heads or wings. Soon all the deceptions and murderous plotting come to a head, though not quite in the way you'd expect.
