So I'm in the backyard under the tree watching the ducklings...
And then I see one of them has a leg that's vibrating. I was like ...what is that?
It kind of was similar to how they vibrate their tails but not the tail but just the leg. She(?) walks around just fine. And she's already about 4 weeks old, so I hadn't even noticed this whole time. And it seems to go away, which is why I partly didn't notice it it until now.
So I don't know if its behavioral, a niacin thing, or even if its a real problem.
The other ducklings don't do it. It was also very hard to get these ducklings, so I don't want to lose even one of them. (These are also black runners.)
The one with this issue seems to act just fine.
But now that I think about it, the other day she wasn't walking around as much as the others. (I didn't realize it might be the same one.)
And also I had them sleeping in the kiddie pool in the basement and I kept hearing like a tiny vibration sound sometimes the last few days. Now I think its her that was doing it.
Is it possible for them to just be nervous and do this, and is this a real issue? (Pic won't show it well. And its hard to spot when she's doing this because its not going on all the time. Could it be niacin deficiency?
