Brooding temperature should be reduced approximately 5 degrees per week until the brooder temperature is the same as the ambient temperature or 70 degrees, whichever comes first. The general rule is that for the first week after hatching, chicks are comfortable at a brooding temperature of 90 degrees.Īs chicks grow and their internal temperature increases, they need gradually less external heat to remain comfortable. If the environmental temperature is too cool or too warm, the chick will experience stress, poor growth or even death. While the chick’s metabolic systems are developing, its body has little by way of internal temperature control. When the chick hatches, its body temperature is about 103.5 degrees. Halfway through development, the embryo produces metabolic heat that raises its temperature to slightly warmer than air temperature. Largely because of moisture evaporation, the temperature inside an egg at the start of incubation is slightly below the incubator’s air temperature of about 100 degrees. The normal temperature of a chicken will depend on the ambient temperature as well as factors such as the chicken’s age, breed, gender, activity level and state of health.Ī chicken’s temperature variability begins from the time the embryo starts developing within the egg. Chickens are different-each bird has an internal temperature that varies greatly. The average human being has an absolute body temperature of 98.6 degrees Fahrenheit.
