How would you rate my atiels diet?

It's good. Watch the walnuts, they are often rancid - buy the freshest. Try shaved carrots, like you shave the carrot a bit at a time with a potato peeler. Bean sprouts sounds really excellent - I like them myself! I never knew why we don't give birds a little apple - rodents take them well. Look into that - sometimes apples cause cramps in people.
