My bird won't eat vegetables at all

I've tried everything — finely chopped, mashed, hidden in other food, on skewers, in foraging toys. My canary refuses ALL vegetables. Fruit is fine but I know they need veggies too. Help!

Did this start suddenly or was it gradual? When my parrotlet did this it turned out to be not enough quality sleep — they need 10-12 hours uninterrupted.

Absolutely love hearing success stories! This gives me so much hope for me and Mochi. Thank you for sharing!
