I am setting up my brooder and I put a 75 watt light bulb in the the lamp. It did not get anywhere near 90 degrees. I did use a curly light bulb thinking it wouldn't burn out as fast. I'm thinking maybe that kind of bulb doesn't get as hot? Anyway I would rather not use the 250 watt bulb because I am terrified of leaving the house with that on. Should I try a 75 watt regular bulb or another curly bulb but 100 watt? The brooder is inside my house and we keep the house at about 71 degrees. Also it being spring time, will these ducks not need the brooder as long? What do you guys use other than the 250 watt? Thanks!
