I have been thinking about this too, because we're going to Pittsburgh for 4 or 5 days the first week in April. Originally, I was going to board the dog, keep the cats in the house and then I didn't know what to do with Ellie. I was going to board her too, but I was nervous because I don't think that the boarding place is that rabbit savvy. But now, I've made the decision to have my mom come and stay at my house with all the animals, thats mostly because I'll have newish chicks and they need to stay cooped up and protected, not all willy-nilly in the yard.
But I was in the same place you are before the hen went broody.
I think if you'll only be gone for a few days, then they should stay at home. Have your mom and sister come and do the basics, like Julie said, leave a simple easy to follow list, lol. They may not get much out of the cage time, but at least they'll be at home. They'll also be really happy to see you when you get home! I think Ellie will feel the same way as your buns, like wth? She probably won't get a whole lot of out of the cage time either, because my mom won't let her out.
I'm sure they'll be fine.
