Maybe, what are the cage dimensions, and how many hours per day does she get to run-around?
Most pet-store cages are pretty small (even the big ones), but as long she gets 4-5 hours of exercise per day, she should be fairly content for a while.
Laying down a lot and playing with toys sometimes sounds pretty normal, depending on the time of day. That said, most bunnies sleep a lot during the day! Mine are most active in the morning or evening, and even then spend long periods lounging, in between bursts of energy.
If you can’t give her total free run while you’re away, you can try attaching an x-pen to give her a “front yard”, so he has a bit more space to run around if she feels like it. You can also rotate her toys if she seems uninterested in them.
