So, a book that I got from the library said to put 2-3 cups of brewers yeast into 10 pounds of chick starter to give the ducklings more niacin (which is needed). I went to the healthfood store today, and they had brewers yeast but it was 20 bucks and my mom want going to pay 20 bucks for 2 cups of brewers yeast. We asked the owner of the store, and she said that they have nutritional yeast and it is actually more nutritious than brewers yeast but is basicly the same thing. Is it ok to mix 2-3 cups of Nutritional yeast with 10 pounds of feed instead of brewers yeast?? thank you!
