I don't skin them if I am not going to use them right away. I put them in the freezer, hide and all. The skin is an airtight seal and I have had rabbits frozen for almost a year with no telltale signs of burn.
When you are going to have a cook up, all you need to do is take them out and leave them for about 2-3 hours and they will thaw enough to remove the skin easily. The stomach can be removed as one almost solid chunk as it will still be frozen to some degree. It makes a lot less mess too!.
I cook them up in a slow simmer in Guiness with tons of onions. The gamey smell when you skin them is not at all like you will taste. For an even nicer treat, try bottling them.
DAMN! Got a urge to set up a line this weekend!
