check. First select the high-product species, check the species purity of the breeder farm and the production performance of the breeder, and whether the breed is bred according to the matching system and follow the breeder farm acceptance regulations. Check the breeding management level and hatching level of the breeder farm, understand the immunization program and antibody level of the breeder chickens, and whether the breeder farm has had an infectious disease.

touch. Hold the chick in your hand, and touch the fat, the size of the abdomen, the absorption of the yolk, and the condition of the body. The healthy chicks felt struggling, well-balanced, moderately weighed, flat and soft on the abdomen, and moderate in size, indicating that the yolk was absorbed and the umbilical cord healed well. Weak young hands feel weak, weak, soft, and the abdomen expands.
