I clipped Louise at first, thought it would slow her down and make her safer. It did not. She was more determined to fly. With full feathers, she is much safer and I marvel at how tight of a turn she can make, almost helicopter-like. With her, I don't have to cover windows but watching the door vigilantly is a must! No one comes in or out unless she is secure in her cage-except I can get the dogs in/out fast with a small crack--but not if she is in the same room as the door. She has flown to the screen and clung on so I know she CAN make it outside. I would be less worried about the crashing and more worried about keeping doors and windows secure.
