You understand the principle behind a solar oven? Or how about that original little girls' oven using just a single light bulb a bunch of decades ago? What was it called, Suzie Homemaker?
They both function by magnifying the heat source using reflective materials. Like the Mylar "space blanket" I mentioned in my above post. That's the only way I see a 25 or 40 watt electric light bulb working well enough to heat 25 chicks.
