I'd go with option # 3. If they don't work out, keep them overwinter and then release them. They will never be Call duck tame. Heck, they won't very likely even be 'mallard tame'.
Edited to add that I hate pinioning right along with you.
I absolutely will never pinion, nor do I like clipping wings... but at least ducks molt 2x per year, so it doesn't last too long... I can understand pinioning something like quail when they're bred for meat and eggs, since the buggers are notorious for "popping up" and bashing their heads into cage tops... I couldn't do it though, just don't feel it is right to permanently take away their born abilities... but I have learned (the hard way) the prudence of clipping wings for safety reasons when necessary...
Oh, you know as well as I do that we both were just excited and drooling. I absolutely, positively do not blame you in the least! Its not your responsibility to educate me. I should have done my homework.
But guess what I have discovered? The picture of the teals came from a website, possibly the place she bought them (logo was cropped out), but I was kinda led to believe they were her pictures. I'm still searching for the other photo online somewhere....
I still feel guilty as all hell...

Well, that is BS... I was wondering about the pics myself, especially considering the one pic had a bunch of males and only a single female... why the heck can't people walk out and take a simple pic of their own?
