Please, I have lighting questions regarding laying hens. We are planning to use a heat lamp only in the coldest of winter with our mature laying hens connected with a thermostat plug in so that it only comes on at 35 degrees and shuts off at 45the degrees to keep them laying through the winter. Will the red light coming on once in awhile bother them? What about a blue light? And I am planning on keeping a very small nightlight on in the barn to help ward off nighttime critters. What if I use a red xmas light bulb in the nightlight to get them used to it? Thanks for any feedback!
