I'm darned if I do darned if I don't! My two month old ducks are dying

[cgjsmith]

I moved my ducklings down to the barn (which I am now calling the death trap!!) and last week one of them came up dead so I treated for coccie like I do for any chickens I put down there. theywere fine for about a week and a half then all the sudden one more showes up dead and another bearly moving. If I let them free roam theres a chance of a falcon pair who lives next door gettng them. Any suggestions (I have a duck house in the works.) Crystal

Are there any pesticides or anything like that in your barn that the ducks could be getting into?

Way too many possibilities.
You need to tell us how you are raising them etc.
