Below Zero Chicken House

I had to give away most of my beautiful little chicken family but did so to a very good home.  I kept three chickens.  I had to downsize my chickens because when we moved, we were too old to move the chicken house we had built for them.  It was the most perfect and secure chicken house in the world, to us.   It was insulated and large with two windows.  They loved their home.

But anyway, we no longer have even a decent chicken house now but we'd had to make due. Then the weather turned frigid reaching 0 degrees and lower at night.  So Larry found a red heat lamp and put it over the water and apparently it is working.  No frozen water this morning.  But I do wonder how the chickens feel about the red light; can they see okay?  They have such bad eyesight anyway.
