Molting can make them more sleepy and standoffish. She also could have been picked on out in the yard if she is acting lethargic or unwell. Try offering just her some chopped egg and plain yogurt if you can separate her.When all of this started I noticed that her lower feathers were kind of sticking out. Yesterday it looked more strange and today I found a ton of her feathers all in one spot in the yard. She had been off by herself. Maybe a juvenile molt? Could that make her not eat for a day or so and not want to sit?
