<p>A method and apparatus for automatic sexing of a one-day-old chick (10) which includes inducing the chick to lose its equilibrium and voluntarily spread its wings. An example of an apparatus which causes chick disequilibrium includes a cup (40) with a rim (42), a funnel (38) removably seated on the rim, and a free-rolling ball (43) inside the cup. A second example of such an apparatus includes a conveyor belt, a mechanical vibrator attached to the surface of the conveyor belt, and two poles for supporting the spread wings. A third example of such an apparatus includes a passageway enclosed on both sides whose bottom is attached to an oscillator. The wings are caused to be spread so that chick sexing can be performed by photographing the chick, applying appropriate image processing to the photograph, identifying the sex of the chick from the processed photograph, weighing the chick, and processing chicks based on sex and weight. Preferably, the chick is photographed in blue light, using a digital camera (48). <IMAGE></p> |
