It's all about the chick behavior. They'll tell you if they are comfortable or not. No thermometer or thermostats needed.
This is what you're looking for:
Inside the house you probably don't need more than a 60-100w bulb and it gets warm in that room during the day you may even want to unplug it altogether.
This time of year in my brooders in the open part of my workshop I turn the lights off every day. Outside temperature will go into the nineties by about noon. Come dark I'll turn the lights back on. All of which are 65w floods. Anything larger is just too much heat. In the winter and spring I may use anything from 125-250 watts depending on the age of the chicks/poults and the current weather conditions.
