A brooder system includes a stock tank having opposed sides, a pair of attachment members each having a first portion secured to one of to the opposed sides of the stock tank and a second portion having a vertically-extending passage, a cross member having first and second end portions downwardly extending into the vertically-extending passages of the attachment members so that the cross member extends over the stock tank, and a heat lamp secured to the cross member over the stock tank. The cross member can be slidable within the vertically-extending passages to adjust a height of the heat lamp over the stock tank. The cross member can be flexible and elongate to bend to form an arch over the stock tank.

A method for reducing the negative effect of heat acclimatization for the hatching of a poultry hatching egg is provided. A special light source is used as an ambient light to hatch the poultry hatching egg. The special light source is light-emitting diode (LED) monochromatic blue light with a light intensity of 20 lux to 50 lux and a wavelength of about 450 nm, such that the light can reduce the negative effect of heat acclimatization at a hatching stage of the poultry hatching egg. The method can reduce the levels of oxidation products such as malondialdehyde (MDA) and corticosterone in a chicken embryo during heat acclimatization at the hatching stage of the poultry hatching egg and increase the expression levels of antioxidase and heat shock protein (HSP) genes, and the special light source reduces the metabolic heat production of the chicken embryo.

A radial fan for an incubator for poultry eggs and newly hatched poultry. The fan has a longitudinally-elongated, hub and a plurality of self-supporting, radially-extending, fan blades on the hub. Each blade is laterally deformable, so that it is deformed by air pressure in a counter-clockwise direction when the hub is rotated in a clockwise direction and is deformed by air pressure in a clockwise direction when the hub is rotated in a counter-clockwise direction.

The present invention relates to a method for promoting production of female embryos in fertilized eggs, comprising steps of :incubating said eggs; generating at least one type of energy with a predetermined energy profile; and simultaneously generating a pre-determined profile of a non-energy parameter by means of an energy generation device, applying both energy profile and the non-energy parameter to the eggs; and, collecting the eggs; wherein said method is non-toxic to the embryos, the application of both the energy profile and the non-energy parameter increases the fraction of females in the hatched chicks.

The sex of embryos in eggs is influenced or controlled through the application of light having selected wavelengths in order to promote the development of embryos of a selected sex. An incubating device is provided having an interior cavity that can be sealed from an outside, and having a plurality of lighting elements disposed on each of a plurality of trays disposed in the interior cavity. Eggs are disposed on the trays, and pre-determined environmental conditions are applied to the interior cavity to promote hatching of the eggs. Concurrently with the application of the environmental conditions, the eggs are irradiated according to pre-determined lighting conditions. The lighting conditions include applying light having wavelengths substantially concentrated in selected ranges, such as light wavelengths within the 390-419 nm, 410-450 nm, 420-450 nm, 450-495 nm, or other narrow range.
