How Hot Temperature Affects Chickens

Birds do not have sweat glands. To lose such heat, they mainly depend on the evaporation of water from the surfaces of their lungs and air sacs. Evaporation turns liquid into vapour and the rate of evaporation increases with higher temperatures. Studies show that to convert water to vapour, heat and energy is required to separate molecules of water from one another, but as water vapour is lost from the surfaces of the lung, heat is lost from the body which, in hot and humid conditions, when the deep body temperature rises, birds would drink more water to reduce the heat that means that they would eat less which, could lead to the birds not being able to have the target weight that the farmers need.

It is also important to know that the number of breaths per minute for bird rises when the heat level is too high and that is called panting. A rise in deep...
