Dont lock her up. When she's reintroduced with the others, there will be picking and pecking/fighting going on and you dont want that stress.
Since she's young, give her time for her egg laying innards to 'get it right', then she'll lay on a normal basis. She simply may be a slow layer, you cant compare her to the Leghorn egg laying machines that they are.
As long as she's eating and drinking, scratching dirt, foraging, preening etc...acting like a chicken should, everything is fine and she'll lay eggs when she's ready.
