Hi! Need some advice???? Last year one of ducklings developed angel wing and I have read that protein is thought to be a factor with the developement and niacin should be added to the diet????? My question is how much do you use ???? Also I read that Brewer's Yeast contains niacin and can be used to supplement also.......again I am unsure how much and which one is the better choice????
