I assure you you won't overheat those chicks using that light in a big tote or bigger area. Its impossible to hurt them if they can move farther away. Yours don't have enough room is all....you may have to raise or lower the light to adjust it that is all.Cardboard boxs can be used to make a sold fence they can't get out of.Its all you need.I'd throw that tote back in the closet for another day as its cost you too much already.But like I’ve said using those recommendations I have cooked several different batches of my chicks before. So usually I keep it lower and watch the chicks behavior to tell me if I need to adjust the temps of the lamp. The chicks know what temp is to hot or to cold better than what something on the internet and research says, no chick is the same so I try to do things based on what they are telling me. I’ve said this many times before in my climate it’s usually around 80 to mid 80 where my chicks were comfortable and happy. At 95 with the room temperature at high 70s the brooder temp went into the 100s roasting my chicks, low to mid 80s and watching behavior of the chicks has worked well for us for almost 6 years now. I have never lost chicks brooding indoors until these last two orders, my chicks that I hatched out myself about a month ago and all the other chicks I hatched were brooded this way with no problems whatsoever.
