cameragirl, we do the same thing, too! They do love it! I have also made them cooked tomatoes. I love our girls.
I was just going through the seed catalogue from the farmer's co-op - they have the sort of seeds grown for animals and forage. I'm thinking of growing some oats and field peas, both in the garden and loose on their range. I realize I'm lucky I can grow these sorts of things, here. The arid conditions the OP lives in would require a very different skill set.
