I'll be getting 15 day-old chicks on the 27th of this month (Oct). My coop doesn't have any available electric. I've racked my brain and THINK I have a workable way of running an extension cord from the GFCI receptacle at the back of my house. The extension cord that I'll be using is the 100 ft. cord that I use to run my hay elevator & is of a slightly larger gauge than the cord on my heat lamp shield. To avoid heat build-up in the cord due to the impedance of electric flowing from a larger cord into a smaller gauge cord, I'm thinking of running the extension cord into a surge protector & then plugging the heat lamp into that...the idea being that, should there be an overload issue, the surge protector will trip and, if it doesn't or the overload is significant the GFCI at the house will trip. I honestly don't forsee any problems, though, as I'm running only a 150 watt ceramic heat bulb like those used in reptile aquariums. Temps this coming week are to be in the low to mid-60's with nighttime lows dipping into the upper 30's. If I'm successful in having a flawless trial run with my intended heat lamp set-up, would it be safe for me to brood day-old chicks in the coop from day 1 or should I brood them indoors with the heat lamp for a few weeks until they feather out before transferring them to the coop with the heat lamp?
