A group of startled chickens teamed up to kill a hungry fox after it broke into a coop with 3,000 hens inside.
The intruder believed to have entered through an automatic hatch door which closed immediately behind it and trapped it inside.
The chickens then grouped together and pecked the predator to death with their beaks in a frenzied attack.
Its dead body was found by a staff member the next day, according to reports .
The unusual incident took place at a farm in Brittany, Northern France, that houses up to 6,000 chickens.
"There was a herd instinct and they attacked him with their beaks," said Pascal Daniel, head of farming at the agricultural school Gros-Chêne.
"It had blows to its neck, blows from beaks," Mr Daniel told AFP news agency.
The coop is kept open during day and most of the hens spend the daytime outside, according to AFP
"A whole mass of hens can arrive together and the fox may have panicked in the face of such a big number", Mr Daniel told the regional newspaper Ouest France.
"They can be quite tenacious when they are in a pack".
This is not the first time that such an incident has taken place.
In 2012, a fox bit off more than he could chew when he sneaked into a chicken coop for his dinner.
Proud cockerel Dude and his three hens fought after they knocked their perch table on the fox’s head then pecked it to death.
Owner Michelle Cordell, 43, was stunned when she went to collect eggs from her garden and found the dead fox and Dude strutting around unhurt with hens Izzy, Pongo and Pecky.
The mum-of-two said: “I’ve never heard of anything like this before. It’s like the revenge of the chicken.
“The little table in the corner of the coop which the chickens perch on had been kicked over and was lying next to the fox’s head.
“It seems they kicked over the table, knocked the fox out then pecked it to death. The fox had little blood marks on its legs where it was pecked. It was not a cub but it was only young and Dude and Izzy are big birds.
“I reared Dude from a tiny little chick and he has become very protective of the others. He thinks he is human and chases our dogs around the garden, pecking them.”
