What will the weather be like when you brood them? What will your outdoor facilities look like? Will it be a fairly small enclosed coop/run or will they free range? There are a few different things to consider.
We all have our own opinions on how to do this. Lots of different things work. I raise mine in my brooder in the coop. In winter I keep the heat lamp on for five weeks, five and a half weeks if it is much below freezing. One ridiculously hot summer I turned the daytime heat off at 2 days and the overnight heat off at 5 days. There is no set time that I turn the heat off, there cannot be a set time that works for everyone.
In my opinion some people keep heat on much longer than they need to, but that's up to them. A fairly standard time frame, depending on weather of course, is to leave the heat on for four to five weeks, then turn it off. Normally chicks are fully feathered out by 4 to 5 weeks and can handle temperatures we would consider downright cold.
