Well, I will bluntly tell you that your information is incorrect. The only feathers that can be sold are for fly tying and forms of pillow making and quilts such as down. I cannot remember the exact wording, and I'm only typing on my smart phone right now, so cutting and pasting is not an option for me at this minute. In addition these feathers must be individual feathers detached from skin. I certainly believe the intent of the Lacey Act was to protect the resource itself, and now it is buggered up to the point that they don't want profit made from almost any part of a migratory bird.....yes including meat.....as in market hunting from the days of old. The rules may seem archaic, but they are current and not going away anytime soon.
I am on my cell right now, and could send you a link to the 50 CFR's section 20 (when I get to my computer) that will make you call your buddy and inform him how wrong he was. You can otherwise search it yourself and read it for yourself. I would not give you false information. Trust me! State regulations cannot supercede Federal rules but can however be more stringent.
You can tell me what you think you know and I will tell you what I actually know for fact. I don't think anyone is selling waterfowl......for even a penny, but if someone was reading this, I want them to have the correct information is all, and yours is not.
Someone else will back my statement, but I hope you take a few minutes and read it for yourself after a quick internet search.
