I feed 3 ducks about 1/4 cup sprinkled on their food. My feed does not have niacin. If feed has niacin already you can reduce the about.

can a horse foal have these?

I would be concerned about a choke hazard.

Are the oyster shells pure with nothing added? I want to put them in the filtration system in my koi pond, but need to know they’ll be safe for my fis

To my knowledge nothing is ever added to the oyster shells. They may be dusty so a quick rinse will take care of that. I give to my chickens right out of the bag

Great quality for waterfowl!

10/10 hands down best price I've found so far! If you've got water fowl birds you know how important brewers yeast (niacin) is when they're young. It's been absolutely amazing! And with it coming from a family farm makes it that much better

Good value

I have no clue how effective this stuff is. I'm putting it in my dogs food and am waiting to see if he benefits from it. For sure you get a lot of it for the price.
