Agreed, I would still supplement in additional niacin. I also use Purina’s feed, and although it claims to have enough for ducklings, I don’t risk it. You’ll want to give ~1 tbsp of Nutritional Yeast per cup of feed. Supplement until they’re fully feathered, at around 8 weeks old.Thank you, I have another question. I’m currently feeding them purina duck food that has niacin in it do I also need to be supplementing them additionally if so what do you suggest I get. I’m new to this whole duckling thing…Thank you.
