Title: Can chicken skeleton be made edible?
Question: I like to preserve as much as possible from my cooking and trash as little as possible.  With that in mind:   can chicken skeleton be made edible?  or is there a way for the bone marrow to be extracted and cooked?   Or does it exist a reason for why it is a bad idea to consume chicken skeleton?

Answers:
sents: text: Chicken bones have a tendency to 'splinter' when 'mashed' (as in chewed upon), which is why you never give chicken bones to a dog.
text: This applies equally to humans, if we gnaw on a chicken bone it is more like to create a harmful splinter that may find itself lodged in any number of places in your digestive system.
text: That said, as has been commented above, extracting the flavorful marrow and those 'last little bits' from the carcass can be achieved by making stock.
text: If you are wanting to reduce the waste, I would then recommend drying and grinding the remaining bones to provide calcium into your compost.

text: Other articles suggest that some people do this, but I would still conclude that it is not safe to do so, though apparently it can be done.

sents: text: Absolutely!
text: My wife makes her own dog food out of 1 Lb of rice, 1 Lb of carrots, and the trimmings of 1 whole chicken.
text: After she breaks down the chicken for the meat that the family will eat during the week, all the trimmings, including the bones, are put into a pot and boiled so we get the marrow and gelatin from the bones as well.
text: I'd describe it as making stock except that the liquid is not separated for reasons I'll get back to.
text: Once the 'chicken stew' has cooked, she finds all the bones and puts them into a high-end blender to render into a thick paste we call a 'bone shake'.
text: She puts the rendered bone into the the stew / stock along with the rice and carrots to finish cooking.
text: Once that is done
text: she adds vitamins and other supplements to the batch before dishing out portions for freezing
text: and then we have dog food for several weeks.
text: We have used everything from the chicken, including the skeleton .
text: We joke that the dog eats better than we do and have had multiple vets give their approval.
text: Now, for those who ask what this has to do with human food, my response is even though we use this process to feed the dog, there is nothing special about it and would be perfectly safe for humans.
text: The bones are completely rendered in the sense of cook time and safety.
text: Cooking them in the stock makes them safe from a bacteria perspective and using the blender essentially grinds them into particles so small as to eliminate any issues with splintering.
text: In fact, my wife started to make (dog) cookies by adding sugar, flour, salt, etc.
text: I mention this to illustrate the multitude of uses for the bones so there is no reason why the bone shake couldn't be incorporated into other recipes for people.

sents: text: We recently made a chicken bone stock by cooking a carcass in water with a few tablespoons of vinegar.
text: When it was done, the bones had demineralized enough that they could be chewed thoroughly without any difficulty nor observable splintering.

sents: text: Torigara (鶏がらスープ) is a common Japanese recipe most commonly associated with the making of ramen.
text: The recipe usually calls for a whole chicken carcass or chicken bones and using a very long cooking time (eg.
text: 5 to 10 hours)
text: in order to reduce everything to a rich broth that can be made into a ramen.
text: Some recipes call for discarding the bone while I am aware of some ramen shops actually pounding the soup and keeping the crushed bones (which renders down to powder) as part of the soup.
text: The recipe is common in ramen shops all around the world and is safe to consume.
text: PS, I think the addition of rice-vinegar in some recipes would help breaking down the calcium in the bones faster.

text: I’ve heard it’s good for arthritis.
text: It made over a quart to drink!
