You do not need paperwork to own a Canada goose. You have to have a permit to sell or give away Migrating Birds.. They are not illegal to own. You can buy them from several hatcheries and ebayers have Canada goose eggs for sale. Some of the ebayers send a copy of the proper paperwork with the eggs, some don't. You can always ask before bidding if they will be sending the necessary paperwork. I've had Canada geese for 7 years. No one cares. Haven't been to prison yet. I put red food coloring in their pool so that neighbors (we have a ranch) know that the pink Canadas are mine.
It's strange the way people just make up stuff. Or like the guy who said his neighbor takes eggs from their nest. You're right - that's illegal, but I'm sure he knows that... Just seems like sometimes people miss their years of being the student hall monitor.
