Lights 12 hours on /12 hours off is applicable when they are 4 or 5 months old and starting to lay. When they are chicks, the one and only purpose of the lightbulb/heat lamp bulb is to keep them warm and it needs to be on 24/7. The guidance for chicks says to start at 95 degrees F when they're one day old, then decrease by 5 degrees every week till you get to "room temp". You move the light further away, thereby decreasing the temp, as they get older. When they are fully feathered at 6 weeks you can turn off the heat lamp and they can regulate their own temp. In your case, once you get to the ambient temp during the day you could actually turn it off during the day, but if the temp drops after sundown I'd turn it back on at night.
