The babies are still not able to fly when leaving the nest and spend some time on the ground. I was lucky enough to see the two different chicks during this period of their life. If you run into these little creatures hiding, and in plain sight on the ground, don't stress. It is a crucial phase of life. A simple rule of thumb, keep the dogs and cats away and don't touch the owl. Usually, at week seven, the babies have all the essential tail and wing feathers to fly.
