She doesn't look old enough to lay yet. Looks like you still have some weeks to go yet. When the comb and wattles get much larger and really red, and she starts to squat for you, the eggs will be coming down the pipe. For now, keep her on starter or grower feed until she starts to show signs of laying. As Drumstick Diva has said, put some fake eggs in the nest boxes now to get her started in knowing where you want her to lay.
Great to have you aboard and welcome to our flock!
