The first is that the eggs cannot be stored for too long. The shorter the preservation time of eggs, the smaller the impact on embryonic viability and the higher the hatching rate. Generally within 7 days after delivery is appropriate, 3 to 5 days is the best. When the egg is stored for a long time, turn the egg once a day during the preservation period or place the blunt end of the egg down so that the egg yolk is in the center and prevent adhesion to the eggshell.
Second, the environment in which the eggs are preserved should be appropriate. Eggs should be kept in special warehouses. Curry should be kept clean, tidy, free of dust, and must have drafts and rats. Curry temperature is best 12 °C ~ 15 °C, egg bank humidity to 70% ~ 80% is appropriate.
