MY duck is having the exact same problem. She is walking on her other foot, using her wings to balance herself and shakes from straining to hold her weight. It has been almost a week. I am going to try the B complex. Did your duck improve?Update: it’s been 3 weeks and she still is not able to walk. We’ve been giving her vit b complex as recommended from TSC as well as nutritional yeast sprinkled on her food. There was a little bit of improvement but then it stopped. She is always in a different spot in coop when I go out there in the morning but during day I don’t really see her move at all. I decided to let her swim (supervised) to let her clean herself and at least move a little bit. She swam fine. But on land seems to step on her left foot and uses her wings to balance (when she tries to move but typically just stays still). She can use her wings just fine, as that’s how she flies out of the water
