Our heat lamps are even above my head when I'm in the chicken coop and they are secured in with hooks that you can't get them off of unless you really push. I know that most people probably don't have a coop that big, but it's just what works for us. We have to heat a 64 sq ft chicken coop, and the lamps have been our go-to.I would never use heat lamps in my coops, too much chance of starting a fire and it's completely unnecessary, detrimental even. What I do use are the heated dog waterers. The wattage is much lower and they are thermostatically controlled so they will not overheat if they are left dry. Liquid water is vital and it's a real pain to break out blocks of ice every day, only to have it freeze again soon after. I'm building new coops this year to expand our operations and a top priority is to design in strategic locations for the heated dog waterers.
Good husbandry without a lot of work is my goal for this winter.
