I'm very jealous

. William and Louis love rabbit, but it's an occasional treat for them because it's expensive to buy from a butcher's shop and I don't know anyone who shoots, which would be a cheaper option.
The general rule for the amount of food to be fed on a raw diet is between 2 and 3% of ideal bodyweight for an adult dog. Puppies need more. Riley is sort of in between at 1 year old, so it will partly depend on how much more growing you think he may do and if you think he's a good weight at the moment. Difficult to guess, but it would be a similar guessing game if you were switching from one kibble or wet food to another.
If you think he's pretty much finished growing I would start him off at 3% of current body weight, so 11500g x 3% = 390g raw food per day. As the rabbit is more of an experiment than a switch to raw it won't matter if that's a bit high or low. It sounds low in comparison to 600g Lily's Kitchen wet food, but I'm not sure how to make a comparison between that and raw.
I think the main thing to consider is the amount of bone in each meal. Is Riley a careful eater when you give him chicken wings or does he try gulping them down? If he's careful he should be fine with rabbit bones. If he's a gulper you're probably better holding onto a bony rabbit portion (pliers may help you get a better grip) while he eats it to help slow him down and crunch the bones up.
You should also think about how much bone you give per meal. He won't really be used to digesting bone, so if you give him a bony meal then I'd make the next meal bone free to help him avoid becoming constipated. Some dogs digest bone better than others. For instance I know from experience that Louis copes well with more bone than William, who had terrible constipation a couple of times before I adjusted his diet to stop it happening.
Hope he enjoys the rabbits
