What product do you have ? NutriDrench is one that probably would be used safely in chickens, but you really need something with riboflavin on the label. The Pouktry NutriDrench does not have riboflavin, although Poultry Cell does. Human B complex tablets can be used for riboflavin and other B vitamins, and dosage is 1/2 tablet daily given orally or crushed in a small bit of food.
