So are you putting them in before dark, or after dark? If you get them in before it gets dark, then they should get used to settling down to sleep inside.
I can think of two ways to get them in:
Put something tasty inside, then shut them in when they go in to eat.
"Something tasty" might just be their usual food with some water added--chickens seem to really like it that way.
Or herd them in. Just walk toward them, so they walk away from you--and keep steering them toward the doorway. Then shut them in.
If they're so tame they'll stand still and get stepped on, herding won't work. But as long as they're willing to move a little away, it does work. No need to run and chase, you just want them to wander calmly the correct direction.
