Methods for controlling poultry barn environments

A method for controlling the environment within the interior of a poultry barn for domestic fowl raised for flesh comprising the steps of:

• (a) illuminating the poultry barn environment on a cyclical basis repeated a multiplicity of times each day,
• (b) purging air from the poultry barn environment on a cyclical basis, said purging cycle comprising at least one purging phase and at least one normal phase, each said phase comprising a frequency, an intensity and a length, said purging cycles being coordinated with the illuminating cycles and at least one said purging phase occurring in an unillumination phase to purge the barn of dust when the domestic fowl are inactive;
• (c) fluctuating the temperature of the poultry barn environment on a cyclical basis, said fluctuating being effectuated in part by purging air from the poultry barn to lower the temperature, said fluctuating cycle comprising at least one target phase and at least one colder phase, each said phase comprising a frequency, an intensity and a length, said fluctuating cycles being coordinated with the illuminating cycles and said colder phase occurring in an illumination phase to stimulate feeding by the domestic fowl,
• (d) sprinkling the poultry barn environment on a cyclical basis, said sprinkling cycle comprising at least one wet phase and at least one dry phase, each said phase comprising a frequency, an intensity and a length, said sprinkling cycles being coordinated with the illuminating cycles and said wet phase occurring in said illumination phase to remove dust from the air and to wet the poultry barn environment for an active stage of the domestic fowl;
• and
• (e) adjusting said frequencies, said intensities, and said lengths of said phases of said illuminating, purging, fluctuating and sprinkling cycles with each other.
