Chickens sense of touch is very similar to ours. They have sensory nerve cells that enable them to feel pressure, touch, pain, heat and cold. Their nervous system tells them also about limb position. Chickens don’t look at their feet to know if one of their legs is up in the air or if both feet are on the ground. Along with the feet, the beak is the chicken’s primary tactile connection to the world. Sensory nerve cells are located throughout the beak and help chickens negotiate fine movements when exploring, foraging for food, preening, building nests and in social interaction.
