My ducks are walking in their knees!

[OldParsonageFarm]

I have two ducklings that all of the sudden are walking on their knees and not their feet. What may have caused this? They are in there own little pen now and get water therapy 3 times a day but it isn't really helping. Help!

What have you been feeding them? Have you been giving them niacin? It could be a niacin deficiency.

Agree with Pyxis..ducklings need extra niacin if they eat chick starter. You can supplement by adding nutritional yeast or Brewers yeast at 1tbsp per cup of feed.
