A new chick production method and a new chick production system are obtained which are different from a conventional method in which all live eggs are collectively accommodated in a hatcher tray to develop chicks. The chick production method of the present invention divides mid-hatch eggs into a plurality of groups based on physical information measured for the mid-hatch eggs during a period from when the eggs are accommodated in a setter tray to when the eggs are transferred to a hatcher tray, and accommodates the mid-hatch eggs in the hatcher tray to develop chicks. In addition, a chick production system of the present invention includes a measurement unit, a sorting unit, and an accommodation unit, and the chicks are developed by each of a plurality of hatcher trays.

An incubator (10) includes: (i) a housing (12) defining a chamber (14); (ii) an air inlet (16) for introducing air into the chamber (14); (iii) a first air outlet (18) for discharging air from the chamber (14), the first air outlet (18) being spaced from the air inlet (16); (iv) a stack of operatively vertically spaced first trays (22) disposed within the chamber (14), between the air inlet (16) and the first air outlet (18); and (v) a first means for tilting the stack of first trays (22) on a plane substantially perpendicular to the direction of operative airflow from the air inlet (16) to the first air outlet (18). A stack of operatively vertically spaced first deflectors (26) are disposed operatively upstream of the first trays (22) for, in use, dividing the airflow from the air inlet (16) to the first air outlet (18) into streams of airflow directed over the first trays (22); and the incubator (10) further includes a second means for tilting the first deflectors (26) on a plane substantially perpendicular to the direction of operative airflow from the air inlet (16) to the first air outlet (18), in use to align the first deflectors (26) with the first trays (22).

An improved poultry production method comprising providing dry hydrogen peroxide (DHP) to poultry eggs, chicks and birds, and devices for providing DHP to poultry production during laying, incubating, hatching, and growing.

An incubator includes a housing defining a chamber, an air inlet for introducing air into the chamber, and a first air outlet for discharging air from the chamber. The first air outlet is spaced from the air inlet, and a stack of operatively vertically spaced first trays is disposed within the chamber between the air inlet and the first air outlet. A first tilting mechanism is provided for tilting the stack of first trays on a plane substantially perpendicular to the direction of operative airflow from the air inlet to the first air outlet. A stack of operatively vertically spaced first deflectors are disposed operatively upstream of the first trays for dividing the airflow from the air inlet to the first air outlet into streams of airflow directed over the first trays. The incubator further includes a second tilting mechanism for tilting the first deflectors on a plane substantially perpendicular to the direction of operative airflow from the air inlet to the first air outlet to align the first deflectors with the first trays.

Provided herein are methods for promoting production of male embryos in avian eggs, utilizing a composition which includes Ginseng extract, Vitamin D and/or folic acid. Further provided are systems for delivering one or more substances for promoting the production of male embryos in avian eggs via a humidity unit of an incubator in which the fertilized avian eggs are incubated.

Provided herein are egg hatching incubators having a reduced operational noise. In particular, provided are egg hatching incubators configured for affecting or promoting the sex of egg embryos using soundwaves at specific frequencies, wherein the operational noise of the incubator does not interfere with the transmitted soundwaves. Further provided are systems including the incubators and methods of using the same.

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.

A controller for controlling illumination emitted by lighting elements within an environment comprising animals and a respective filter between each of animal and the lighting elements, the controller configured to: control the lighting elements to emit illumination having a first spectral composition for a first time period to produce, on a first side of the filter, a first level of illumination as experienced by a visual system of the animals; control the lighting elements to emit illumination having a second, different spectral composition for a second, subsequent time period to produce, on the first side of the filter, a second, different level of illumination as experienced by the visual system of the animals; and control the lighting elements to emit illumination throughout the first and second time periods to maintain, on a second side of the filter, a minimum level of illumination as experienced by a visual system of the animals.

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.
