The invention relates to household appliances intended for agricultural purposes and can be used for the incubation of eggs from any poultry bird at a homestead or a private household as well as in small business or for breeding poultry in small quantities. The small-sized incubator comprises a housing, preferably having the form of a parallelepiped, configured to have a frame structure； a heat-insulating cover, a heating element, a humidifier, a fan, at least one egg tray configured to rotate eggs, a temperature sensor and a humidity sensor, a control unit configured to be connected to a backup power unit, according to the invention, the said frame housing is configured to be assembled and disassembled with connectors； the said heating element is located on or directly above the inner surface of the heat- insulating cover； the incubator is equipped with an emergency fan located on the top of the housing. Further, for another embodiment of the small-sized incubator which differs from the first one in that the humidifier is configured to be a high- frequency membrane equipped with a reflector, which, according to yet another feature of the invention claimed, is located above the membrane at an angle from 30° to 60° to the membrane. The application of the present invention allows us to create an energy- efficient small-sized incubator characterized by highly-reliable operation in a given range of air temperature and humidity by positioning heating, ventilation and humidification elements in the design of the incubator and, at the same time, by improving the ease of its operation and providing an opportunity for thorough cleaning by configuring the housing and the heat-insulating cover of the incubator so that the said elements are made assemblable and disassemblable.L'invention concerne des appareils ménagers destinés à des fins agricoles et peut être utilisé pour l'incubation d'œufs de toute volaille au niveau d'une maison ou d'un foyer privé ainsi que dans des petit
