My advice to you is.....stay indoors, keep warm.
I'm never having all that much luck with rabbits during the winter. They are around but not for long, and they don't stray far from the warren. It your desperate for a rabbit stew, set up a hide about 20 yards away from the warren at either dusk or dawn. Or better yet, chuck a ferret down there!
All the best, Aaron
