Fred is a small boy who lives with his mum and dad and big brother, Jim. After a farm visit with his school, Fred develops an itch. To his horror, peculiar and dramatic changes then begin to occur to his body and the dreadful thought that he may be turning into a chicken starts to become real.
When Jim starts teasing him and convincing him that he really is turning into a chicken, Fred becomes even more troubled. These troubles are greatly increased when his mother summons the doctor to examine him. Fred, however, is a determined and resourceful little boy who endeavours to stay one step ahead.
But will his problems disappear, or will his worst fears be realised?
