Will my rabbits be ok outside in the cold?

Its not good to keep them outside. I live in Ca. where winters don't ever really get all that cold, and a friend of mine left her family of bunnies outside, and they all froze to death despite the lack of severe cold. Bunnies are really sensitive. And whats worse is that you shouldn't keep bunnies outside in the summer. They overheat faster than they freeze. If you reallly really don't have anny room for them indoors, I would cover their hutch with a blanket and tarp to make sure that wind doesn't blow through there, and rain doesn't get in... uness its a waterproof hutch then a blanket should work just fine.. just make sure theres a little slit so air can get through. But really that isn't guaranteed to work if you live in a very cold place.
