BTW, heat lamps certainly DO warm a space.
i think what fetchdog means is that heatlamps are designed to warm objects not space (air) as do ceramic, hot air, or open flame heat sources. there is of course residual heat from the bulb and dissipated heat from the objects the lamp is...
don't cut back on the ventilation trying to save heat. you'd be better off suppying a heat lamp and leaving the coop a little loose, not drafty, but well ventilated. i friend of mine wrapped his in plastic to deal with winter and created more problems than it was worth.
