Just this afternoon I ordered 2 heat lamps from Premier 1 because they look very safe and are enclosed. Now I read about the fire justmandy had today and I am just a little freaked out about using them no matter how safe they may be. I wish I could show you the pic. of them but don't know how to get it here. We live in the Western N.C. Mountains and it was extremely cold last year. All my chickens and ducks are adults and I have seen some say they don't need heat. At what temps should someone add heat if at all? I guess I could send these back if I change my mind.
