Bunnicula,
From your veggie list, I just wanted to mention that the buns should not get a lot of broccoli ....it causes gas and that can make them sick and cause a lot of pain. Likewise green beans are a no-no as well.

Good veggies are the romaine and boston lettuces, endive, green or red leaf lettuces, lots and lots of dandelions, radicchio, collard greens, beets, radish leaves, and of course their very favorite carrot with tops...most any lettuce except iceberg. Herbs...dill, parsley, watercress, cilantro, etc. Many buns like kohrabi, bok choy and napa cabbage too. Red clover is great if you can find it.

The following can be given out but should be limited due...these are high in some mineral, the name of which I have forgotten:
kale, which I am convinced all buns love dearly;
mustard and turnip greens, spinach, only the dark green outer leaves of cabbage (the pale inside leaves have no nutritional value and for my buns too much can cause loose poop), broccoli,
cauliflower. They can have a small amount of fruit once in a while: apple, strawberries, blueberries preferred. An occasional raisin or grape but they are high in sugar and can cause runny poop. I hear a little fresh corn is ok but then I hear it's not a good idea...it is also high in sugar. Absolutely no bread, rolls or cereals... yeah that sounds strange but I was at my vets and this woman came out with 2 huge, horribly overweight rabbits and she was bragging about how they loved hot dog buns! Some folks have no sense.

I'm sure I've left things off but hope this helps you get some ideas of what they can have. I've been meaning to mention too that I'm so pleased you've got the bunnies inside and i hope it works out for you. Take care!
