Busy Bun

So we like to let our rabbits have a lot of "free range" time, and during their free range time the buns have been working on a fairly impressive warren that they've built into a mound of dirt. Now they usually do a bit of digging, and then spend the rest of their time grazing and hiding behind the wheelbarrow. Except today I went outside to check on them and found this!! The little bun has been carrying bits of grass in her mouth from the lawn to their burrow! I'm not quite sure what she's preparing for, but she was all business today!
