Duck can't walk sometimes?

I don't know what you should do for her in the meantime, hopefully someone else can help with that. Just out of curiosity what feed were they on before?
Wishing all the best for Mocha.

Usually we get Purina's Layena or a 15% protein feed (I can't remember the brand) for both our ducks and chickens. They seemed to do pretty good on those.

For the as long as I can remember or cared to know i had fed my ducks and chickens the vibrant life layer pellets and vibrant life cracked corn. But then we switched about three to four weeks ago to an all flock feed and my pekin has been doing a lot better and same with all the rest of the flock. Maybe the stuff you had been feeding them, has more niacin. I was just thinking.

The symptoms sound neurological in nature. If it hasn't been dropped, I'd assume it's dietary. Mazuri starter feed is one I can highly recommend, but we still put this in the water the first 6 weeks: https://www.strombergschickens.com/product/Probiotics-+-w-Electrolytes-&-Vitamins-200-g

We're keeping her in a kiddie pool while we keep an eye on her.
We noticed today, she has been keeping weight off her right leg.

This is how her poop has been looking

Did you check the bottom of her feet for bumble foot?
