I've only harvested once but the videos I watched showed to wet down the rabbit after dispatching but before skinning. I did wet it down and had no problem with the hair getting on the meat.
x3 I see no reason so wet the rabbit as I get very little hair on the carcuss. At times, I have held back the food and water for 12 hours. I do prefer it, but don't always remember to. I get a bit annoyed working around a full bladder.
I didn't. I didn't have any problems, other than the bladder was full, but it wasn't a big problem. Also didn't have hairs on the meat. I did rinse it's after, just to get the extra blood off.
Ive never heard of getting them wet. Sounds messy.
As for withholding feed. I don't bother. Although if your going to butcher it does seem silly to waste a days ration.
I like to wet my rabbits down before skinning. It's just a lot easier keeping the hair off the meat. As far as feeding them... well, I give them the choice of anything they want for that last meal.
I hang mine up on a gambrel. I have not noted hair being a problem. what little does get on the carcass rinses off easily during the cold water soak phase. I like to soak the carcass in a saltwater with a dash of vinegar for a few hours. The vinegar just inhibits bacteria growth. The soak is done in refrigerator.
