I would agree with the Canada Goose, theory. Yep, use it on an arrow. Or you could slice the thick part of the quill on a diagonal and fold the point up into the quill body, and wrap it, and run a thread, or sinew thong through the loop of the quill, and attach it to your quiver, either on the bottom, the middle, or top part. Good Medicine there!
How do you cook those geese? Everyone I hear talking about them, it is like eating a tennis shoe! I have plenty of Canada geese in Montana. Some say they just eat the breast meat, and pound the snot out of it, before cooking it. I would hate to throw the legs away. I like the thighs, and drum sticks best anyway. I have Friends who used to hunt ducks, and just pop out the breast, and toss the rest. I hate that!
Anywho, that is pretty cool that it just floated to you. What part of VA are you in? Are you in a fly way?
