9 Week old Pekin duckling with crooked leg

[Duck~Diva]

So i bought 6 Pekin ducklings from a local TSC store on the first day of spring and they have all been lively and well but about 3 days ago i noticed that one of my little drakes has a leg that seems to be injured but when i inspected him he showed no obvious pain/stress from it and it's not hot or inflamed.He's tripping over his own feet constantly. It seems to have started from his knee area if that makes any since. It dosen't seem to be bothering him in any way but but it is getting worse and i need to do something before he gets too old in which it grows to be permanent. Will post pics if able.

It sounds like niacin deficiency. What are you feeding (be specific), and are you supplementing their feed with niacin or brewer’s yeast?
