Duckling rapid death help!

[Luv Ducks]

How are they now. Did the new ones die too? What kind of food and bedding did you use? What about your water? Is it tap water or well water?

So sorry to hear this. I have never heard of new ducks disease. I have just been very fortunate with mine that they have all ended up healthy. I pray that yours make it. I use city water with mine and have used well water with some before too. They all did fine. I use pine shavings for bedding and only something made for ducklings, right now it is Purina Flock Raiser that mine are getting.
