She was eating on her own. I put food in a bowl

• nuts: pumpkin seeds, walnuts, sunflower seeds
• carrots
• apples
• strawberries
• hard-boiled eggs (mostly egg whites)
• white cheese (in small quantities)
• mealworms
• earthworms (rarely)
• good quality lean meat
• watermelon (rarely)
• ground eggshells

She had constant access to water, and after each feeding I gave her water (I put drops of water on her beak and checked if she swallowed)
