So let me start off by saying that I've read several threads on supplemental heating in the winter, and would not really consider using a heat lamp or other source, as I live in southeast Louisiana. However, a couple weeks ago, one of my girls started molting, and has now lost nearly all the feathers on her neck. To make matters worse, the other one was recently attacked by a hawk (I got to the scene before the hawk did any significant damage) and now has a couple patches of raw skin showing where the hawk tore out her feathers. As it is projected to be in the low 20's (teens with wind-chill) over the next few nights, should I hang a heat lamp nearby for warmth? I believe I would really only need to do this during the night and early morning until it warmed back up.
