Why would a hens comb turn a lighter color?

A hen's comb may turn a lighter color due to several factors, including changes in health, stress, or hormonal fluctuations. For instance, a hen that is sick or under stress may experience reduced blood circulation to the comb, leading to a paler appearance. Additionally, during the molting process or when laying eggs, hormonal changes can affect the color of the comb. Environmental factors such as temperature and lighting can also play a role in its coloration.
