Standing straight, walking backward with tail down

[EchoRose]

My ducking is approaching 5 weeks and she just started standing straight up and walking/waddling backwards like she lost her balance, keeps her right leg and left wing kinda funky, she has full mobility, and swims just fine but I'm not sure why this is happening. I ordered B3 vitamins but I'm not sure it's her legs, I'm really worried. I've never seen this before, has anyone else experienced this?

Her internet is sporadic due to Helene.

As for the situation, definitely try a full-complex B, as well as start adding additional Niacin. I've only had this happen once and was unable to rectify it and unfortunately had to put the duckling down.
