My juvenile hens are not roosting

[McKinneyMike]

I have 6 pullets with 2 of them being 9 weeks old and 4 that are 7 weeks old. They have yet to migrate to their roost area. They huddle in one corner of the coop and sleep as clutch on the floor. Will they start using the roost soon? I have a ramp built and the two oldest ones can fly up to the roost as they do it regularly.

Patience is the name of the game when it comes to chickens

They are still young, so give them time.
