Okay, I've heard mixed thoughts on having a heat lamp in my coop for nights when the temp gets below freezing. Today was our first day of cold and the girls stayed inside half of the day. I felt kind of bad for them and am thinking they are allowed to have a little heat! I don't know if I can sit in my warm house all winter thinking about them out in the cold (although yes, I know they are barn animals!!). I'm ok with spoiling my birds and footing the electric bill, but I don't want to screw them up in any other way. Will they be strung out all day from the blaring red heat lamp at night!?? Will they turn into complete babies and never leave the coop on cold days? Will the inconsistency of it being on/off based on temps (which vary tremendously here) stress them out? I'd love any and all opinions. I only have 3 chickens. Coop is 4' x 6' with an always-open pop door, 2 (closed) windows and a variety of vents here & there. I turn a regular 60 watt bulb on for them at 3 am each morning. Thanks!! I'm slowly but surely earning my self-bestowed PhD in Chickens due to the countless hours of learning I do on this forum!!!
