They maintain several nest eggs usually by maintaining a common area where the chicken’s nest. They are protective in nature and will attack other roosters entering their territory. Usually, during the day, a rooster will sit at a high place and function as a scout for the group, hence the name ‘rooster.’ A rooster usually crows at any time.
