People think chicks need the brooder to be much warmer than it needs to be. Chicks are usually perfectly content with no heat source during the daytime when it's above 75F during their first week. I assume this is their first week, anyway. You just say "new born".
I have two four-day olds and they are outdoors since yesterday at around 75F. They do have a broody hen to stuff themselves under should they chill, but they are spending surprisingly little time under her. According to the Gospel of Heat Guidelines, they should be suffering since it's not 90F. The reality is much different, needless to say.
Chicks will need more heat at night despite the ambient temps because they are sleeping and not taking in calories. So even during a warm spell, you will need to supply a bit of heat at night for the first three weeks, but try to provide the minimum only so the chicks appear comfortable.
During the warm period in summer, very often you will only need a 100 or 75 or even a 60 watt bulb when using a lamp. A 250 watt bulb will literally cook your chicks if the ambient temp is also very warm.
Don't lose sight of the reason we supply a heat source for baby chicks. It's not to warm the brooder! It's there for the chicks to replenish lost body heat. When they've warmed back up, like we would at a campfire, they move away from the heat. If the entire brooder is 90F, there is nowhere for chicks to shed excess heat. They keep accumulating heat along with the heat their bodies generate from food calories, and they then begin to experience heat stress, showing up as pasty butt and lethargy.
