i wouldn’t clip her wings. If you clip her wings she can not flight from predators anymore.
You’re Rita is still young and playfull.

I had my Dutch chickens on the roof (not on top) too when they where young. Now they don't bother or try anymore.
Imo its better to play a trick and give a few healthy treats when you want the chickens to go inside. If you do that every evening, the chickens learn very quick its party time

and time to come home. (try treats like mealworms, sunflower seeds, corn or tasty grains, these are oke as an extra)
