Listen mainly to the calls of chicks. Good and healthy chicks are loud, crisp and short; weak chicks are weak and hoarse or screaming.
Touch the chicks in their hands, touch the fat, the size of the abdomen, whether the absorption of the yolk is good, and whether the posture is even. 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.
