The importance of instilling the concept of...
A hen does not need a rooster to lay eggs. However, a hen does need a rooster to fertilize its eggs, otherwise the eggs will not hatch. If the egg is fertilized, the mother hen or a broody hen will care for the egg by keeping it warm until it hatches. While developing, the unhatched chick will eat the yolk in the egg to get the nutrition it needs to grow and develop. Rich in food value and liquid, the yolk provides a newly-hatched chick with all the food and liquid it need for the next three days.
How long does it take for a chicken egg to hatch?
A hen lays an average of 300 eggs per year. When a hen is "broody," it means she wants to hatch her eggs. The hen will sit on her eggs to keep them warm so that they will hatch into chicks. A fertilized egg starts developing into a chicken when its temperature reaches 86 degrees fahrenheit. A chicken takes 21 days to hatch.
