You can stop calling them chicks whenever you like.

Once they feather out, (about 6 weeks old) I call them "the teens".
Once they hit "the teens", they are big enough to go out in the coop, in an area fenced off from the rest of the flock so they can all see each other but not touch.
Depending on the temps, I have a heat lamp hanging above both a low roost and a higher one for Jack, my surrogate mom. Some times they will use the lower roost, but Jack usually coaxes them up to the higher one since I have ramps going up to both of them. (Jack is so old, he can't jump or fly as good as he used to). When it is cold out, the lights run all the time. Once the weather starts getting over about 45* during the day, the heat lamps go on dusk to dawn mode (my coop is usually about 10* warmer than outside). You could use a thermocube if you want.
If they are finding the food & water in your brooder, they should be able to find it in their coop, provided you didn't hide it on them.

Roosting, as well as eating & drinking, are instinctual. If you provide it, they should find it. Usually. There have been a few dumb clucks around.
If I don't have a heat lamp going, I always put a night light out in my coop just in case someone gets knocked off, so they can see to get back on the roost. I hope this helps you.
