I am soooooo sorry. We had some ducklings shipped and only one arrived alive. We have had them shipped since with no problems. Sounds like it could have been a niacin deficiency? Don't let it put you off ducks. They are wonderful! Try again and start giving them a Poult Pack (Metzers) and extra niacin (not the flush free or no flush stuff). Add 100mg crushed into 1 gallon of water. I had a Rouen who was having leg problems and this treatment worked within days!
