Amusing footage of backyard chickens having a big fight over a single slice of pizza.

The video, filmed in Minnesota, USA yesterday, shows the chickens chasing after each other when one of them manages to get hold of the food.

The filmer later wrote online: "We had a piece of pizza left over so I decided to give our girls a treat.

"They each started trying to get away with the whole piece for themselves."

"No chickens were harmed in the filming of this video," he continued.
