read the first 5-6 pages
The Migratory/Ornamental Waterfowl INFO Thread
https://www.backyardchickens.com/forum/viewtopic.php?id=345303
I started this thread to teach every one about migratory waterfowl.
In the later pages, it also has all the species which require the federal permit as well as links as to how to get it.
Just google
US FISH AND WILDLIFE SERVICE MIGRATORY WATERFOWL SELLS AND DIPOSAL PERMIT
It will come right up.
Just to own them, you need nothing on a Federal permit level, cant speak for your own state laws, most require nothing but your state DNR will be able to tell you.
On the sell, the seller has to have a permit, yes they give you a form 3-186 . This is you possession permit, keep it and show it if ever asked. Now if you decide to transfer them in any way dead or alive to another person, you must have your own permit.
Wood ducks and all migratory species have been kept in captivity for centuries. These are all captive population birds. Yes it is illegal to go out and collect your own, very illegal.
All captive birds must have the 3-186 permit and be marked in one of 4 methods.
Wood ducks are the cheapest and most common by far. you can buy yearling pairs in the fall for $40- $50 every where, dont pay more than that, they just arent worth it.
The A.P.W.S. and Gamebird Breeders Gazette are two publications that specialise in the sell and trade of these birds and have about 15 pages per issue of classifieds. there is also several forums dedicated to them. Cant mention their names here though for BYC policys.
Anyway, read threw that thread I linked, it will help you a lot in care, housing feed pretty much any question you may have. If you have more after that, feel free to ask away
