This all depends on where you are going and how you are traveling. How will you keep them warm while you are traveling?
As far as the issue of a red lamp vs regular bulb? They don't see as much of the red light so it's thought to be less stressful for them. A plain, white bulb is a glaring light on them 24/7. This is not natural of course and it can stress them, especially if there are other stress factors already, like overcrowding.
If you decide to leave them at home and use a 35 or 45 watt bulb...test it out before you leave and make sure it's warm enough underneath it. Week old chicks need a place to go to warm up that's about 85 to 90 degrees. I don't know how close to them you'd have to place a 35 watt bulb to get the temps needed for this age of chick.
