Goose Stopped Eating

[GooseGirl98]

My goose hasn’t eaten in several days. I separated her from my ducks about a week ago, because she was injured, and the ducks are always chasing her around. I’ve since noticed that she hasn’t been eating her food. She’s as light as a feather when I pick her up. I’m scared she doesn’t have much time left, and I lost another goose to similar symptoms. None of the vets near where I live know anything about geese.

What's the nature of her injuries? Any chance of internal damage?
What are you feeding? Lettuce and fruit are never refused in my house. Is she drinking?
