Baby is totally bare on the belly because, in a state of anxiety, she plucked her feathers so much in her previous home. They'll likely never grow back. And Baby's mangled feet will always be a reminder of where she comes from.
"Her owner was a breeder/hoarder," Kail Marie, founder of Tallgrass Parrot Sanctuary in Kansas, explained. "If you see her feet you'll see that they are at a 45-degree angle. When Baby was still young she was not given perches and had to hang on the side of her cage. Her leg tendons slipped pulling her feet up like that."
