Calcium requirement

How many chicken wings does a lab puppy, approximately 15 weeks old, need daily. He has been eating 2 wings and eggshell (about half an egg). He chews on bones and naws on mutton leg/hoofs frequently. He has a wide variety of ground meats with organ and mixed vegetables three times daily. He weighs 14 pounds. I had found on the internet that 2 wings would equal approximately 1100 mg of calcium. Are you able to tell me if you think this is a correct number of wings for him? I am using 50mg/kg for an adult weight of 50 pounds, roughly. Thank you for your time.
