The quality of eggs is not only related to the success of the hatchery, but also has a great impact on the quality of chicks and the performance of the chickens. The quality of the eggs is good, the viability of the embryos is strong, and the hatching rate is high. The egg selection method is: A look at the appearance. Eggs should be clean, there should not be feces, egg liquids and other dirt on the eggshell; eggs evenly weight, hatching rate of eggs is too large, too small chicks are also small egg weight 50-65 grams is appropriate. The shape of eggs is good, and hatching is the best. Those who are too long and have two round tips must be removed. Moderate eggshell thickness, too thick steel eggs, thin sand eggs, wrinkled eggs can not be used as eggs. Eggshell color should meet the requirements of this species. The second is listening. Hold the three eggs in each hand and turn the fingers, so that the eggs and eggs collide with each other to hear their crisp sound, broken eggs can hear the sound of cracking.
