(Help) Duck limping

This is an informative thread about niacin deficiency. Perhaps you'll find the info about dosage for niacin there. Hopefully you have a type that is for animals.

Hello!

I have 2 Pekin ducks, one male, one female. I keep them in my garden where they have more than enough space.
Yesterday, in the middle of the day, the male duck started limping
Today, it's gotten worse, and now he's mostly sitting down, only getting up to drink (from a tall cup I have for him to clean his nose in) on one leg, while he holds his other one up.
There's no signs of any damage on his foot as far as I see, and I can't feel anything weird by touch either.
He's not making any unusual noises either, and he isn't running away.

How can I help him? Last time the female duck had some health issues we bought some vitamins (that are put into water) so we gave them those again.

Could be too he hurt his leg. I've had this happen with a couple of my boys... Too rambunctious when mating or getting chased/kicked out if the pool by the other boys. Within a week was better. Is he eating?
