An incubator tray includes a body that defines: (i) a first surface and a second surface that defines a sealed void therebetween; (ii) an inlet that permits inflow of fluid into the void defined between the first and second surfaces of the body; (iii) an outlet that permits outflow of fluid from the void defined between the first and second surfaces of the body; (iv) a plurality of bores that extend between the first and second surfaces, through the void defined between the first and second surfaces; and (v) a temperature sensor associated with each bore.

The current invention relates to Method for incubating a poultry egg on a hatchery, the hatchery comprising: an egg storage section configured for storing eggs, an incubating device separate from the egg storage section and configured for incubating eggs during an incubation period at an incubation temperature, the method comprising the steps of; receiving in the storage section a number of eggs at a time of arrival, storing a number of eggs in the egg storage section for a heating period in storage of at least 1 days, and transporting the number of eggs from the storage section into the incubating device, incubating the number of eggs in the incubating device during the incubation period until hatching occurs, characterized in that the method comprises; determining a temperature course over time to which the number of eggs should be exposed based on the time of arrival and desired moment of hatching, wherein the temperature course over time at least comprises a temperature increase during the heating period in storage in the storage section from an initial temperature to a set temperature between a physiological zero and the incubation temperature,
heating the number of eggs during the heating period in storage from the initial temperature to the set temperature.

An egg incubator with a precision adjustment function of humidity includes a hood, a rotation frame, and a host portion. The hood is provided with an incubation compartment. The rotation frame is arranged in the hood, and includes a housing, a fan, an exhaust valve, a humidity sensor, and a main control circuit board. The housing is provided with a work compartment, a circulation air inlet, a circulation air outlet, and a valve opening. The housing is provided with a humidification tank. egg incubator is provided with an internal circulation air path and an external circulation air path. When the air humidity is less than a first preset humidity threshold, the main control circuit board controls the exhaust valve to close the valve opening; when the air humidity is greater than a second preset humidity threshold, the main control circuit board controls the exhaust valve to open the valve opening.

An egg storage system includes an egg storing section configured for storing eggs during a heating period in storage prior to incubation. The egg storage section is configured to heat eggs from an initial temperature to a set temperature. The egg storage section comprises a temperature control system to control a temperature in the egg storage section according to a temperature course over time to which the number of eggs should be exposed. The temperature course over time to which the number of eggs should be exposed is based on a determined time of arrival and a desired moment of hatching, and the temperature course over time at least comprises a gradual temperature increase during the heating period in storage in the storage section from a measured initial temperature at the time of arrival to a set predetermined temperature between a physiological zero and the incubation temperature.
