I know I am like a broken record here - but I still think her sight holds her back. Probably makes her cautious to try new things - like that time Bob when she didn't eat off your hand but only ate what the others scooped to the floor.I may be saying something ridiculous but is it possible that she just doesn't want to grow up and become independent ? I know this is a very anthropomorphic way of saying it. But maybe she acts like she was still a chick ?
She also has some childhood to catch up on given leg and sight.
She made such good progress on the leg I wouldn't give up on her!
