Hatching Chicken: 3 of 8

A white leghorn chick emerges from an egg (image 3 of 8). From the time the eggshell is broken to the time the chick emerges is approximately 22 hours. The chick starts by breaking the eggshell with a sharp part of its bill. After an air hole is created in the egg, the chick will take several hours rest before enlarging the hole. The normal incubation time for a chicken egg is 21 days at 37 degrees C (100F). The eggs must be turned three times a day and kept at the correct humidity level. Leghorns are one of the best-known breeds of chicken. They produce the majority of the worlds crop of white eggs.. Stunning Photo Gifts From Science Photo Library
