Heat stress and exhaustion is one of the top causes of chicken death. For those new to backyard chicken farming, it is important you learn to recognize the signs of this serious condition and how to keep your chickens cool and hydrated. Chicks, especially, need extra attention to help them remain healthy. For a flock of laying hens, knowing how to prevent heat exhaustion and treat a chicken suffering heat exhaustion is important to preserving their health and the health of their eggs. Once your chicks are old enough to move outdoors, remain vigilant for signs of heat stroke, especially if it’s mid to late summer. Heat stress comes on quickly so it is important to watch them closely. Even older birds need supervision during the hot summer months
