Jack-Jack and the return of the chickens

After caring for baby chimps in Africa, Jack-Jack is enjoying his new home until the arrival of the 'chickens' in the garden marks the end of peaceful mornings and gives him a new set of challenges. He's convinced Ronnie the rooster is out to get him. Is he paranoid or is this cheeky chicken on his case? Luckily, Jack's too busy fossil hunting in an actual mammoth graveyard and appearing on TV with a special thermal imaging camera to see how fit he is, to let a rooster ruffle him.
