4 week old duckling has problem with legs

I fixed the videos.
The vit D I dont plan on giving again anytime soon. Just wanted to give a little extra. Some of what the joint supplement has is manganese, anti inflammatorys, zinc, and various nutrients from mussels. That I don't plan on giving again at least for now. Was an extra boost.
Does anyone have like articles I could look at that shows research into how much niacin ducklings need? Or fast growing animals in general?
The niacin total that day wasnt 10 mg. I meant the supplemental total was 10 mg plus the 11.5 mg would make it 21.5 mg.

We have found that really helps them so much faster and better is the Durvet liquid B complex it's easy to use and if you feed it to them over treats you know exactly what they are getting. I am having computer troubles let me go find the correct link again

This is what I was looking for [Niacin is fairly easy to find, here. It is a dietary supplement. It supports neurological development. I think it would do no harm to add 100 mg per gallon of water to their drinking water for a month or so. If it is a niacin (B3) deficiency, I would expect to see improvement within a week to ten day ]

mainly the amount they need daily. Please try the liquid b complex it works so much better and quicker and is easier to use if given over treats!

quick update
She did a little bit of trying to join in on running with her buddy for fun today. Ankles still look about the same. I still don't know if there's swelling or a bone growth thing related to injury or deficiencies.
She's still good at climbing, she can climb onto my stomach or back when I'm laying down. Or when outside onto something like a pile of dirt from the garden.

I think Manna Pro duckling starter feed might seem inadequate because of the issue the cayuga is having but the feed probably is adequate. The actual owner of the ducklings did not buy the duck feed in advance, so she had made some homemade duck food. I found out later she had just guessed the amounts of each ingredient used for it. They got the duck feed 9 days later. Corona virus made shipping slower. Should have asked someone who has amazon prime to purchase the food. Or checked out a feed store. But it did not come to mind at the time.
Possibly the Buff duck got off to a better start. She was bigger when we first got them. Maybe ate more of the grow gel in the shipping box.
Anways not an ideal start for their development but thankfully it wasn't terrible.
Small aside, I think it would be good if they find a better way to attach the cup or different container to carry the grow gel. The staple's sharp points was exposed because the cup had fallen off at some point. Looked like it didn't hurt them so that's good.

So on a Metzer farms blog article and in Dave Holderreads duckling book which I learned recently I could borrow it online through my library, they both mention 10 mg a day for 3-4 weeks old. I don't know why you say they need more than that Isaac. Therapeutic dosage?

Poultry pedia, which was mentioned in other threads, is pretty informative. I like that the info presented on leg issue stuff was all together in one place too.

Leg issue is at least not getting worse. It's been about one week maybe two. Still giving the b complex I have.

I've heard 100mg a day for each duckling, I'll have to look back on my sources and get back to you.

In my book by Dave Holderread he says [If feeding chick starter /grower satisfactory results can be achieved by 100mg of niacin to a gallon of drinking water. 0-8weeks old] Now we all know from experience that so much water is wasted that is why when a ducklings is having issues already We have learned from experience that the Durvet Liquid B complex works faster and better at getting them over a niacin deficiency.

I was thinking I should double check if I had read 10 mg. I don't know why I thought I read that in Dave's book. Maybe asides from Metzers I read 10 mg elsewhere or I was thinking that Holderread is about the same with amounts of supplementation. But yes it's definitely not 100 mg - 150 mg a day per bird. That's the amount that can be put into one gallon of water as one way to give niacin.
Under the Health and Physical Problems chapter of his book for niacin deficiency prevention it says 35 mg per pound of feed for 0-2 weeks of age. 30 mg per pound of feed for 2-10 weeks of age.Using Metzers numbers again for feed consumption for a 3-4 week old pekin duck that would be 10.5 mg a day if the bird is eating .35 lbs of feed that contains 30 mg /lb.

Update:
The ducks are doing good. Seems like the buff duck is still the better one with moving around on her legs. She'll crawl under things that the cayuga doesnt. But maybe that's partly a height difference by just a bit. Cayugas are a little bit bigger than buff ducks. The cayuga is not noticeably walking weird anymore. I'd have to really look to see if there is any weird walking.
