Hi everyone I have six five week old hens and shut the red heat lamp off today. It was way too hot for it. Still too hot to turn back on, and probably will not. They are in my garage that is quite cool in there. Although I did put a floor fan in there to circulate the air around. I had the garage doors open all day and it stayed cool. Should I leave a regular light on at night or off? So hot out today - I'm pooped!
If it's warm enough, just leave it off. Mine lose their light at that age and are kicked outside even if it's 40 at night.
By 8 weeks mine go without a light. Last summer when I brooded chicks I gave them a 100 watt light bulb for warmth on the cold nights.
