I realize that those who are convinced their birds need supplementary heat will not be convinced otherwise but when we refer to chickens giving off body heat we do not mean that they are heating the room. What we are saying is that the body heat that they are generating is trapped inside their down and feather coat and that is what is keeping them warm.
I also realize that it is difficult for a human to stand out there shivering in the cold and understand that their their chickens are built different and they are not feeling the same thing.
If a caretaker chooses to fuss over their flock and add conditions that nature has not provided for them thats fine but they must also understand that while doing so they are introducing all sorts of undesirable conditions like excessive humidity, weakened resistance to disease, sleep deprivation, un-natural egg laying cycles, etc.
