If the chicks are old enough that they don't need artificial heat I would think it ok to put them in the main coop in a sectioned off area. The adult birds would not normally spend a lot of time interacting with them if they can not easily get at them.
You would quite probably be wise to ensure they are not subject to drafty or damp conditions
Generally quarantine is to prevent your flock from some disease that new additions would possibly bring in, and once you are satisfied that the new birds do not have anything to be concerned with they are integrated into the flock.
If you have a separate brooder house/pen it is probably best to let them grow there for some time prior to the main coop move. A key issue here is the age of the chicks.
