I was just trying to add variety to the diet but realized that chicken quarters had a good balance of meat and bone already together. If I was to offer other meats like beef, venison or moose, there only getting the muscle meat! I would not be able to get the bones and also read that those types of bones (weight bearing) are not to be eaten but more for recreation chewing. Whole fish (mackerel) would be another another substitute to chicken quarters.
