Yes, the stress of the move, plus an adjustment to a new coop could prevent them from laying for a while. Had they started to lay before you got them, and are you sure about their age?
I have a 28-week-old pullet barred rock that just started laying last week, so perhaps your pullets hadn't started laying yet. If the combs and wattles are bright red and waxy-looking, and if the pullets squat or crouch down when you try to pet them, these are good signs that they will begin laying very soon. If the combs are small, dry-looking, and light pink rather than red, they haven't been laying and aren't close to laying.
Give them some time to adjust. After they've learned the coop is home, can you give them access to the outside in either a run or free-range? Birds that have been free-range tend to get stressed when they're confined 24/7.
