LOVES the popcorn in the crockpot. You can also buy the bags of bean soup mix. (I've seen 15, 16, and 17 bean soups), but make sure it's the ones with the seperate seasoning packs. You can simmer the beans in a little water overnight and add them to whatever fresh veggies you give your birdies. Here's two websites that I've found some good birdie recipes at, although not necessarily for the crockpot:
parrot recipes - beans, grains, pasta mix

Enjoy!
