A Frenchman has been given a three-month suspended prison sentence for sexually abusing his pet chicken.

The 59-year-old, who cannot be named for legal reasons, was seen performing the sickening act in the family garage by his daughter, who told her mom.

The horrified mom kept tabs on her partner and one day followed him on a trip to the garage and caught him in the act, a court in Rouen heard.

He had his trousers around his ankles and was at a “stage of extreme excitement” in the Normandy town of Saint-Étienne-du-Rouvray, a suburb of Rouen.

On Wednesday, the court found the man guilty of “sexually abusing a domesticated animal” three months ago, saying there was evidence he had regularly abused the bird.

The court heard that his wife vomited “when she saw what her husband was doing.”

The man’s lawyer added: “My client is clearly very ashamed about this. He and his wife have now separated.”

The chicken has now been given to a new owner, and the man has been banned from keeping pets for life.

Neither the man or any of his family were in court when the sentence was handed down. He also had to pay a fine of around $940.
