Do you have a totally enclosed run or are they free to range when you let them out?
If you do not have a totally enclosed run I’d suggest you keep them locked in the coop for several days, at least four with a week not uncommon. That gives them time to think of the coop as their new home. Otherwise they may go roaming, looking for home, and you may never see them again.
If you have an enclosed run so they can’t wander, you can let them out at sunrise as far as them roosting. They may or may not go back into the coop to sleep at night, but as long as they are contained you can move them into the coop after dark to let them know where they should be sleeping. I think it is a good idea to leave them locked in the coop for a few days (if it is big enough) so they get in the habit of sleeping in there so you don’t have to move them in after dark, but that’s not totally necessary if you are willing to physically put them in yourself after dark.
How old are they and are they roosting yet? My brooder raised chicks tend to sleep on the floor until they are around 10 to 12 weeks old. Some start roosting earlier, some later, but 10 to 12 weeks is fairly normal. I find mine tend to sleep on the ground outside the coop even if I leave them locked in the coop for over a week if the coop is elevated. If the coop is on the ground they tend to go in the coop to sleep, even if they are not roosting yet.
I don’t know if they are roosting yet, if your coop is big enough to leave them locked in there for an extended time, if your coop is elevated, or most importantly if they will be in a run or are free to go roaming. As long as they cannot go roaming you are not likely to have a disaster. You can handle it.
