Just want to give my budgies some good veggies to eat. I haven't noticed green beans on the good or bad list. Are they okay to give to my budgies. Also, what other greens should I give them?

Green beans are fine. Most leafy greens are fine to give your budgie. Pretty much the ones that are healthy for us are healthy for them. Just avoid celery and iceberg lettuce as they are mostly watery and provide very little nutrition. They can cause loose droppings as well. Mine especially love kale, romaine lettuce, baby spinach leaves, and broccoli.

Are celery leaves okay? Because they aren't as watery as the stalk and they are nice and leafy.

They're not very nutritional but Blinkie thinks they're delicious so i keep them as an occasional treat.
