After the chicks hatch eggshells in the hatchery and are transferred from the hatcher, they have already undergone considerable operations, such as picking and grading, individual selection of chicks after hatching, selection of healthy chicks, and removal of weak and weak chicks. Sick chicks, male and female identification, and some have even been immunized, such as the Marek’s disease vaccine immunization for chicks after hatching. To evaluate the spray rate of 1-day-old chicks, it is necessary to inspect the individual chicks and then make a judgment. The inspection contents mainly include:
1.Reflective ability
