How to distinguish healthy chicks from sick chicks

The strength of chicks will not only affect the survival rate of chicks, but also affect the performance of meat production or egg production in the future. Therefore, after chicks are hatched, healthy chicks and weak chicks should be strictly selected and separated, and poor chicks and sick chicks should be eliminated. 1. When healthy chicks hatch normally, the incubation time of healthy chicks is consistent and concentrated, generally from the 20th day to 6 o'clock on the 20th day, reaching the peak at the 20th day 12 and ending at 2 1 day; The hatching weight of chicks that meet the standard of this breed varies with varieties and types. Generally, the hatchling weight of broilers is about 40 grams, and that of laying hens is 36 to 38 grams. The fluff is neat, clean and shiny; The abdomen is flat and soft; There was no bleeding trace in the umbilical region, and it healed well. Tightly dry and covered with fluff. Chickens are lively and active, with big eyes and strong feet; The voice is loud and clear; The touch is plump, plump and firm. Second, sick chicks hatch too early or too late, and the incubation time is delayed for a long time. On the 22nd day of incubation, there are still some unshelled chicks. Overweight or underweight chickens are overweight, thin and underweight due to abdominal swelling and malabsorption of egg yolk; The fluff is unkempt and dirty, lacking luster; Abdominal distension is prominent and slack; Umbilical protrusion, bleeding marks, poor healing, moist surroundings, obvious exposure without villi coverage; Close your eyes, stand unsteadily and be afraid of the cold; Screaming endlessly; Thin to the touch, baggy and struggling.
