At what age can I turn off the lamps. It gets into the 30's at night and the 50's during the days. Most of the flock moves away from the lamps during the days. I noticed yesterday one of the hens was laying on the floor of the coop panting. I turned off one of the lamps and things turned back to normal. The temps at 5' are hovering in the lower 80"s. What should I do? John
