When are roosters or hens likely to become aggressive?

The likelihood of aggressive behavior in roosters or hens is particularly heightened when they feel their nesting area is compromised or when their eggs are disturbed. This protective instinct is a natural behavior in birds, especially during the breeding season or when eggs are present. Hens are known to fiercely protect their nests from perceived threats, which can include the removal of eggs.

While other factors like feeling threatened generally may lead to aggression, it is the specific and instinctual protective response to nesting disturbances that often triggers the most aggressive behavior. The act of removing eggs can be seen as a significant invasion of their territory, prompting instinctual defensive behaviors from the hen or rooster.

This context can help underline the importance of understanding animal behavior in managing poultry effectively, ensuring both safety for caregivers and comfort for the birds.
