Sounds like you did well. I like to toss in about a tablespoon each of rosemary and thyme, then about 10 garlic cloves (unpeeled, I just smash them and toss them in) and an onion (same as with the garlic, skin and all). A piece of ginger about the size of my thumb (chopped) goes in also. I saved the pan drippings and put those in the stock once it was done.
I save all the bones from chicken and turkey in a bag in the freezer, that way I always have bones on hand for this purpose.
