"Corn itself does not raise a chicken's body temperature. It is a carbohydrate source providing energy to the chicken's body. There is an increased energy need during the winter"
What I mean is when you see a study.. something more scientific, where they used hundreds or thousands of chickens groups fed different things like wheat, corn, etc and check the core body temperature of the birds before and after eating the different feeds for comparison. Until then my reasonable deduction tell me that core body temperature is not raised by eating corn.
We ALL have one issue or another and many things we kick our own back ends for.. And yes hormones make us and our young cockerels (teenage kids) and more crazy. Please start another thread about it if you like to try and rally some support.. since it's WAY off topic here.

Oh, and quit your bellyaching and take it like woman!
