What would happen?

My broody hen hatched out 13 babies, I sold 8 of them. Her and the rest of the babies are being kept in a coop right now. The lady I got them from kept her chickens out all of the time, they didnt have a coop, so the hen is used to sleeping in a tree. When I let her and the babies out, will she come back to the coop, or go back to sleeping in the trees? its not safe here to sleep in the trees, like it was at her old home. Or should I just keep her in the coop? Its good sized, 8 feet long, 6 feet wide and 6 feet tall(it was a pigeon house) She flys over all the fencing I had, and I cant find top netting anywhere near me.
What will the babies do? They have been in the coop since they were 3 days old. Will they come back to it?

Once chickens get used to a coop they will return at night. It does help if you have a small light in the coop also.

My banties and cornish crosses go to their coops, but I didn't know if the hen would or not, since she was used to be kept outside all the time.
So the babies will be used to the coop?
