Hi, Ali,
Sorry to have been so long in replying to you- I have been having problems accessing the server, but its OK now, I hope!
I suggest that whatever advice you may be offered about feeding chicken wings, raw meat and so on to your Golden Retriever puppy, you ignore it, and go a for a reputable commercial puppy food. The best of these are compounded after a great deal of research into a growing dog's nutritional requirements and are made from the best of materials.
Different makes provide different foods for breeds of different sizes. dependent on their different rates of skeletal growth an consequent calcium needs. Do not add extra vitamins or other supplemensts - it is all there!
Remember to ask you veterinarian about de-worming, and follw the vet's instructions very carefully about de-worming intervals, vaccinatuionm and so on.
When you go to buy your pup, ensure that you see its mother, to assess her temperament, and, if possible, its father too.
I am sure that you and your family will have many happy and enjoyable years with it.
Walter
