Ok, I'm not the greatest with converting milligrams to tsp so I could really use some help. I had to go back to chicken feed for my ducks since it over $10 a 50# bag cheaper so I bought an 8.8oz (250g) bag of 500mg powdered niacin for them. For the life of me, my brain isn't figuring out how much niacin I need to give 21 adult ducks. I have 12 Runners, khaki Campbell's (2 drakes), 1 Mallard (3 pounds) and 8 Runner/Khaki Campbell mixed - most weight 4 pounds average. They free range so I feed them in the evening once back in their pen. I divide their feed between 3 small dish pans so I'd be dividing the amount of niacin between them.
Thanks in advance.





















Thanks in advance.
