At what age can broiler chicks in feather sexible format be feather sexed?

1. One day old

2. Three days old

3. Day old

4. Five days old

The correct answer is: Day old

Feather sexing is a method used to differentiate between male and female chicks based on the development of their feathers. This technique is generally reliable when chicks are very young, specifically at day old. At this age, the differences in feather development can be observed, as females tend to show more advanced feathering compared to males. The days shortly after hatching are critical because the chicks have distinct characteristics that can be accurately assessed for sexing. If an attempt is made to feather sex chicks after this stage, such as at three days or five days old, the differentiation may become less obvious and could lead to inaccuracies in sexing. Therefore, day old is the optimal time for feather sexing, making it the correct choice.
