    I searched a few times to try and find the answer to this question.....

    So, I'd like to have this post available to all of those that have asked the same question but cannot find the answer... please, folks, by all means add your advice and experiences as well! [​IMG]

    Found my answer here.... http://pubs.caes.uga.edu/caespubs/pubcd/1287.htm

    Here
    is an excerpt....

    Maintaining the correct temperature is crucial in chick brooding, especially during the first seven to ten days of the chick's life. Early in life, the chick is poorly equipped to regulate its metabolic processes to adequately control its body temperature. As a result, the young chick is dependent on environmental temperature to maintain optimal body temperature. If the room temperature decreases, the chick's body temperature will decrease. Likewise, if room temperature increases, the chick body temperature will increase. Chilling or overheating during this crucial period can result in poor growth, poor feed conversion and increased susceptibility to disease. Proper brooding practices must maintain the chick's body temperature so that it does not have to use energy to loose heat by panting or generate heat through metabolism.

    Research has shown that the chick develops the ability to regulate its body temperature around 12 to 14 days of age. The chick can be easily stressed if its body temperature decreases or increases by as much as one degree. Once the body temperature changes the bird will try to compensate and it most cases this means that it will have a negative effect on performance. The body temperature of a day-old chick is approximately 103 degrees F (39 degrees C), but by about five days of age body temperature is 106 degrees F (41.1 degrees C), the same as the adult. Extreme temperatures (high or low) often result in chick mortality, but even mild chilling or overheating can damage young chicks without causing death. While chicks are more tolerant of high temperatures than adult birds, high temperatures for extended periods of time increase mortality and have negative impact on performance.

    Research has shown chicks that are subjected to cold temperature have impaired immune and digestive systems. As a result, cold stressed chicks have reduced growth and increased susceptibility to diseases. Cold stressed chicks will exhibit higher incidence of ascites, a metabolic disorder that results in reduced performance, increased mortality and increased condemnations at the processing plant. In research studies where groups of chicks were brooded at either 80 degrees F or 90 degrees F, the chicks reared under the warmer temperature had better weight gains, feed conversion and livability. Chicks brooded under 80 degrees F experienced reduced growth compared to the high brooding temperature treatment. The chicks reared under those temperatures did not catch up in body weight and as a result weighed less at market age than birds that were brooded properly. Not only do chicks exposed to low brooding temperatures have reduce growth rates, but they will consume more feed to keep themselves warm, reducing feed efficiency and increasing feed costs.


    I'd like to include these words in case someone else does a search.... chicks body temp temperature stay warm heat lamp

    Thanks [​IMG]

    Interesting. Maybe the powers to be can put it on the main part of BYC under the learning center.

    Maybe that's why Lucky is smaller than the hatch mates. It got stressed.
