Natural incubation is when hens are allowed to sit on their eggs and hatch them on their own. One of the disadvantages of this method is that the brooding hens sometimes abandon the eggs. This may happen due to a number of reasons, including disturbance by predators, weather changes, or lack of proper nutrition. When the hen abandons the eggs, they are left to cool and may no longer hatch. In contrast, with artificial incubation, the eggs are kept in a controlled environment, and there is a higher chance of all the eggs hatching successfully.
