If you boil, you cant give them the bones, as cooked bone is a no, no.
The problem with cooking Rabbit, is, it takes about 3/4 hour, so the meat just falls off the bone.
I now skin the Rabbits and using my Opinal knife, cut the meat off the bone,gives you enough for a good meal.the rest go to the Ferts.
i just put in a freezer bag, date it, and freeze for three wks to kill worms, just take the bags out the freezer and its ready to feed.
You can buy a special glove cheap on the net, that stops you slicing your hand, as your knife needs to be sharp.
