Well, you are adding calcium BUT: 1. You are missing a LOAD of other minerals and nutrients so there MUST be cooked organ meats, cartilage, and skin in there. Liver is among the especially useful organ meats. 2. You would be safer grinding cooked bones and then straining them because so many bone meal sources are often NOT food grade and so many are too high in heavy metals like lead. Alternatively, use Tums. It would not hurt to put small amounts of some veggies in there but don't go too heavy on things with much Vitamin D, and NEVER use things like avocado, chocolate, grapes, currents, or raisins. Look below for a link you NEED to use to know which human foods can be toxic for pets. When we had to make homemade food for a sick one who could not swallow properly TWO veterinary nutritionists told us to always add these things: COOKED egg yolks (and the whites were also okay once cooked), and Nutrical. Read what things are dangerous in: http://www.aspca.org/pet-care/poison-control/ You already know that in your location it is important to cook meats sufficiently. Also, a human AND ferret note: be wary of bushmeat. The eating of monkeys is how a simian virus got into chimps and then became the precursor of HIV. Then eating chimp meat brought that into humans and in someone it modified to become true HIV. There were some early cases of HIV found in retained lab samples from people who died of mysterious diseases and had gone into the interior before there were roads in the mid 1950s so it existed before then. Later roads allowed it to spread outward which is why it was seen more in the 1970s onward, and it seems to have developed some additional mutations. There are actually a range of diseases like that, meaning that the more roads that connect jungles to cities, the more there is the outward spread of diseases that were not known to science before. Also, bushmeat in some locations is higher in parasites and sometimes in novel parasites. If Addis Ababa is anything like Paramaribo was when I worked in Suriname (most of my time in the Voltzberg and Raleigh Falls areas) years ago then bushmeat will be available in some markets, and that is common in many tropical nations. Heck, from talks with others in the U.S. there are (were?) Farmer's Markets which sometimes have (had?) hunters' kiosks, including in sometimes areas with ongoing prion disease in elk...
