I have a heat lamp set up in a small coop with 11 chickens. It gets really cold. They love the lamp! !! However, I've been reading about light sources should be turned off, for sleep time. Here's the question, (sorry I know it must be obvious, I want to be sure) does the light source apply to the red heat lamp I use? They hardly ever leave the coop (snow) Thank you!!!! I am super grateful for the site!!!
