That is a possibility? I've lost a few to flushing but they broke their necks, had one that boinked pretty hard and was 'loopy' for about an hour. Others with the low hanging wings, injured their wing while flushing into the side of the pen wire.
It may have injured it but not to a point it's disabling. Just keep an eye on her. I've had more than a few that have injured their wing and have been ok for the rest of their lives. It just sorta hangs down a bit.
