Mountain, if you must go with the 250 watt instead of a couple 100 watt bulbs, be sure the fixture is ceramic. Far too many fires have resulted from the fixtures overheating. Make sure the bulb you use is not coated. The teflon type coated bulbs give off fumes that will kill the chicks.
I built a pvc pole to hold the fixture, with a hook for the chain, so I can secure it with both the chain, and the clamp. That way I can raise the lamp weekly, to reduce the heat.
