Hello! I have Purina poultry starter feed that is unmedicated. It does have Niacin in it however I don’t believe it is enough. I have attached photos of the food. I was going to suppliment with B Complex in their water as I read about 100-150mg of niacin per gallon. Is this complex B ok to use? Is this the best way for me to mix it for them? Thanks in advance!!!
