Will a rooster set on hen egg?

Roosters do not set on hen eggs. The process of incubating eggs and caring for the young is called brooding, and it is typically done by female birds, such as hens, ducks, and turkeys. Roosters are male birds and do not have the same maternal instincts as hens. They do not have the necessary broodiness behavior or the physiological adaptations, such as the development of a brood patch, that allow hens to successfully incubate and care for eggs.
