I'm still unfamiliar with what to feed my diamond dove. His main diet right now is millet and a mix of canary/finch seeds, which the pet store told me was suitable for a diamond dove. Sometimes I'll put in a piece of apple, some broccoli, spinich, or a mashed hard boiled egg. How often should he receive different types of foods? What types of seeds or foods do diamond doves love(kind of like budgies to spray millet), and what other foods should I incorporate?

Are these foods toxic to diamond doves:
- oranges
- banana
- arugala
- chard

Thank you~ I would love to hear some advice
