METHOD AND APPARATUS FOR INCREASING THE QUANTITY AND IMPROVING THE QUALITY OF HATCHLINGS INCUBATED AND HATCHED UNDER ARTIFICIAL CONDITIONS BY EXPOSING THE EGGS TO NATURAL SOUNDS

摘要

A method and apparatus for exposed eggs and hatchlings of precocial avian species incubated, hatched, and brooded under artificial conditions to sound recordings made under natural incubating, hatching and brooding conditions to reduce the spread of time over which the hatchlings emerge from the eggs, to reduce the stress experienced by both the unhatched embryo and the hatchling, and to increase the attraction of artificially incubated hatchlings to feed and water during the brooding stage.
