Conditions still the same as in my last post:
The Orpington coop still has the 60-watt black reptile heat bulb and a 75-watt black regular bulb.
The silkies are roosting/staying directly under the black 60-watt heat bulb ("Reptile Rays GE Blacklight Nighttime Heat Light") that's clamped on a board at the two-foot height. They should be very warm there. If it gets too warm they move to the perimeter of the heat area.
I'm wondering if maybe there IS a BIG difference between the much more expensive black 60 watt "heat" bulb and the regular 75 watt black bulb. To really compare, later when it's warm enough, I'll put a "heat" 60-watt black bulb in one coop at the five-foot level and a "regular" 60-watt black bulb at the five foot level in the other coop. I can't be doing too much experimenting now in this subzero weather.
I just want to find out the magic combination of bulbs/watts to be sure that the coops never go below 15* F again. I know that the chickens can survive in much colder conditions, but there aren't any reasons for them to be so very uncomfortable if a couple of right-size-wattage light bulbs can be used in the worst of extremely cold conditions.
