Many people think chickens are stupid, but they are actually very intelligent and have excellent memories. Chickens also have a strong maternal instinct and will fiercely protect their chicks from predators. The mother hen will often call her chicks to her using a special sound, and the chicks will respond by running to her. The mother hen will then gather her chicks under her wings to protect them from the cold or from predators. Chickens are also very social creatures and form close bonds with their flock mates. If a chick is in danger, the other chickens will often try to help it.
