A kit for converting a multi-stage egg incubator to a single stage egg incubator. The single-stage egg incubator conversion kit includes an air intake system, an exhaust/ventilation system, a heating source, a cooling source, an environmental control system, and humidity system all being capable of incorporation into an egg incubator. Components of the air intake system, exhaust/ventilation system, heating source, cooling source, and humidity system are operatively connected to the environmental control system to provide environmental control within a setter of the egg incubator, including selective cooling capacity, selective heating capacity, selective air flow between the setter internal environment and an external environment, and selective air flow from the external environment into two or more zones within the setter internal environment.

A climate chamber for the treating of products with a conditioned gas stream includes a substantially closed compartment having two opposing lateral walls provided with one or more passages; a substantially closed channel which extends around the outside of the compartment and connects one of said lateral walls to the other of said lateral walls in order to form together with the compartment a substantially closed circuit; and a gas displacement device received in the substantially closed channel for circulating the conditioned gas stream through the circuit. The gas displacement device is provided with a reversing system configured for reversing repeatedly, in each case once a reversing time interval has elapsed, the direction in which the conditioned gas stream is circulated through the circuit. The gas stream passes through the compartment predominantly from one lateral wall to the other lateral wall.

A system and method to promote biological responses within incubated eggs using lighting devices within an incubation chamber. A light supporting device is installed within the incubation chamber in spaced relation to an incubation device housing a plurality of eggs. The light supporting device is positioned to direct light at pre-determined wavelengths into the interior cavity of the incubation device to irradiate the plurality of eggs to promote a biological response within the eggs.
