chickens won't go in coop

[Raydco]

My 23 week old redstars are laying nicely but they go in to the coop only to lay, They do not go in at night or even in the pouring rain. The run is completely enclosed so it is safe. Should I be putting them in each night so they get the idea?

Yes I would keep putting them in there. And if you let them range, a couple of days locked in the coop wouldn't hurt either.
