like waterdog said, they arent really easy to raise from scratch, easy to keep and breed yes, but they can be a pain in the rear to get to that 2-3 week stage.
What are you feeding them exactly?
yes remove the domestics, a few days tops is all they need to be in there, they are food hog and will esentuatlly startve wild ducks to death at times
are you adding anything to the water?
what temp is your brooder at?
are they around any other domestic birds? inside or out
are they just dying or do they have illness symptoms? Runny poop, listlessness, ect.
Just trying to get a round about idea of what you are working with to see if we can get some better results for you.
But Lord no, dont give up, there's someting you're missing somewhere and we can work threw it.
First year birds sometimes dont lay (mandarins) or have weak offspring (possible deal with the wood ducks)
Give it time, the birds will get better for you and you will get better for them. Yopu cant just jump right into these and not expect a hickup along the way. If it were that easy everyone would have them.
Snip those hooks off their toenails too and stop all that climbing. Once they realise they cant get out, they be more prone to settling down and acting normal
But do remember, wood ducks are the most wild of all the captive wild waterfowl. Just something about them. They are and always will be very jumpy and flighty in aviaries.
Might suggest trying some ring or marbled teal next year
