Before you start making a chickens hatchery, you need to decide how many eggs will be incubated in it at the same time. For the chickens hatchery with multiple trays, that is for incubators for more than 50 eggs, you need a fan, which would be stirred the air at a rate not less than 2 m / s and ensure uniform temperature throughout the volume. Otherwise, the temperature of the upper egg tray will be several degrees higher than the lower one, because warm air is lighter than cold air. The chickens hatchery 50 eggs fan is not needed. Temperature uniformity over the area of the tray in such an incubator is achieved by correct positioning of the heating elements.


The walls of the chickens' hatchery must be well insulated. This will reduce the difference in temperature between the center and the edges of the tray. As the heater can be used, for example, polyurethane foam, felt, foam. Incubator of plywood or particleboard should be done with double-walled for better insulation. As the finished hull incubator can use an old refrigerator, cardboard packing boxes, beehives. Footprint incubator selected based on area occupied by eggs. Between the edges of the tray and the walls of the incubator to make the gap size of 5 - 10 cm, for better air circulation. In the manufacture of incubator 50 eggs in the bottom of the box makes 6 vent holes 1 cm in diameter, so they are not obscured by baking the water, which is placed at the bottom of the incubator, to create the optimum humidity in the incubator. Between the bottom of the incubator and the surface on which it stands, it is necessary to leave an air gap size of 3 - 5 cm for the free access of air to the ventilation holes. Carbon dioxide produced during incubation, accumulated at the bottom and exits through the vents. If there is a broken tap carbon dioxide from the incubator, embryos suffocate from lack of oxygen. In the ceiling of the incubator, make the viewing window size 100x100 mm, which covers the glass. During incubation, the glass slides back to provide a gap width of 1 - 1.5 cm. In one of the walls of the chickens' hatchery door, do to change the water in the tray and turning the eggs.

Tray of eggs

Eggs are laid in a tray made of wood in a rectangular frame, which is stretched Nylon, metal or other mesh with a mesh size 5x5 mm. Sometimes homemade incubators used a grid with very fine mesh - up to 1 mm. If the mesh sags under it possible to kill two or three rails. It is not forbidden to manufacture their own metal or wooden bars. Tray bumpers fence height 7-8 cm and mounted on legs not less than 10 cm, or make sliding tray, like a desk drawer. If the eggs turn one, then, lest we forget what has already turned over, and what - no, one side of the shell dagger.

For the simultaneous flipping of all the eggs in a tray set movable frame without a bottom. The width of the mobile frame of 2-4 mm less than the inner width of the tray, and the length is shorter than the tray frame 10 cm between the narrow sides of the frame rails are mounted at a distance of 8-10 cm from each other. Between the laths are placed eggs. When turning the eggs at the same time moving beyond flipped 180 degrees.
