The 80/10/10 numbers for raw feeding is an “average”. But what’s included in the average? Small whole animals whose bones can be consumed and larger animals whose bones cannot! For instance, let’s say a wolf eats mostly muscle/organs from a bison and hardly any of it’s bones because they’re too dense. Just have to keep in mind the phrase “balance over time” when feeding raw. But since you are going by a recipe, your food should end up mostly balanced than not! Liver should ideally be not more than 5%. Sometimes I add more muscle meat and sometimes I don’t. So sometimes my batch is around 30% bone and sometimes near 10%. I’m not exact all the time. I add heart, gizzard, tripe or muscle meat like thighs as additional “muscle meat” and have to do some algebra to figure it all out! For 5 lbs of whole chicken that’s around 30% bone, I can add up to 9.5 lbs of muscle and half a pound of additional liver to make it around 10% bone and around 5% liver. I haven’t seen (or looked for) bone content numbers for whole calf. I use preymodelraw.com for some figures on bone content. This is just what I do. http://preymodelraw.com/page/articles.html/_/raw-chat/common-cuts-a-photographic-guide-to-raw-meaty-r15
