Mandarins are gorgeous but very finicky to breed and raise... I know a couple people with them...
Biggest thing, and this will probably freak you out, you have to DROP them to get them to start eating...
Like 6 ft onto a bed... could you do that with a new hatched little duckling?? They are hatched in trees normally and the mom leaves the nest and goes to water and calls them til they all drop out of the tree... my OH found a vid on it, will see if I can get the link later...
I have read that!! And yes, I could drop one... as long as its onto something soft.

I watched a wonderful documentary on wood ducks, and it is so cool how they jump out of the tree to find momma. Unreal to think they instinctively know to do that so young.
