Chicken eggs need to be incubated at a temperature of 37 - 39 degrees Celsius, either through natural incubation or using an incubator. After 19 to 21 days of brooding, the first crack may become visible on the egg's surface. However, it is important not to assist the chick in breaking out of the shell at this point, as it can have severe impacts on the chick's health, especially if the eggshell cracks on the 19th day of incubation. The chicks should fully consume their food inside the shell. The yolk serves as a nutritive material during the embryonic period, while the albumen (egg white) provides protein for cell development. Both of these play an essential role in the embryo's development. What part does the chick use for pipping?  The Chick's Egg tooth, which is lost soon after hatching, is responsible for pipping. An egg tooth is a small, elongated bone above the upper mandible. The chick's neck muscle, called the pipping muscle, helps it reach the egg surf
