The invention discloses a poultry egg hatching machine, comprising a box body, a door, an egg turning device, a humidifier, a ventilator, a heating device and an electric control box, wherein the eggturning device, the humidifier, the ventilator and the heating device are arranged in the box body, and the electric control box is arranged on the box body. The egg turning device comprises egg carriers and an egg driving mechanism for driving the egg carriers to turn forwards and backwards; a plurality of egg holders are arranged on the egg carriers vertically at intervals, each egg holder comprises a plurality of holder bases for holding eggs respectively, and each holder base is provided with an illumination device for providing light to the egg. The illumination devices emit light to poultry eggs; as each illumination device emit light to one poultry egg and is close to the egg and most of light of the illumination device is gathered on the poultry egg, illumination intensity and illumination quantity to the poultry eggs are ensured to be uniform without big difference, and thus, growth of embryos is improved, hatching rate is increased, and hatching time is shortened.
