I know that it's good for tegus to get nutrients from eating entire chicken or poultry carcasses, but I need to know a few specs. Raw innards and organs are what I'll buy from the farmers market to feed to zzyzx, but I also heard that chopped up raw bone is a great source of calcium. Here's my question: my family eats pre-cooked rotisserie chicken all the time and throws out the bone. Could I use this cooked bone as food or is it too difficult to digest once it's cooked?
