Before I got my ducklings, I contacted Nutrena, and this was their reply
From Nutrena-
Thank you for your inquiry and for visiting our website. It is best to start your ducklings on NON MEDICATED NatureWise Chick Starter. Continue the starter feed for the first 7 weeks and then you can switch over to All Flock 18% (Country Feeds or NatureWise). All of our poultry feeds have Niacin. The NatureWise Chick Starter has 185 mg/kg. The All Flock is 125 mg/kg. The NatureWise Meatbird is 81 mg/kg. The niacin requirement for ducks per NRC is 55 mg/kg. Additional supplementation is not required but no harm if you want to add some brewers yeast. Brewer’s yeast is a very good B vitamin source as well.
Yes this was similar to my reply but I only asked about the different lines not exact formals.
with whatever you can find I'm sure.
