Hold the chick in your hand.
After the chick has eaten, squeeze the chick gently right below the breast to induce it to squirt fecal matter into a container or on the ground. You don't need to save this; it's just to clear the bead so that the next step isn't any dirtier than it has to be. Be gentle to avoid injury.
Place pressure on the bird using your thumb and forefinger to spread the ventral surface of the cloaca upward to expose the eminence, called the "bead" of the bird. The cloaca is the common cavity into which the intestinal, urinary and generative canals open in birds. Although this sounds straightforward, the bead of a male and a female look so similar that it usually takes an expert to determine the sex of chicks. In the male the bead is typically convex, while in the female the bead is flat or concave. Professionals often describe the female bead as pointy and the male beed as round.
Work quickly as extended examination is stressful on the chick.
How to Find Out a Chick's Gender
Sexing chicks when born is important to avoiding conflict between male and female chicks and to save money. Males kept with females will take a disproportionate amount of the food and water, and breeders need to be certain that they are properly feeding the females to promote future egg production. Also, males need to be culled because fewer of them will be needed for future production. However, unlike most animals determining the sex of baby chickens is often difficult because the sex organs are internal, and there are not external signs of sex until several weeks after birth. By using certain techniques, professional sexers tout success rates of more than 98 percent.
