I like Flock raiser crumble because it's an all flock feed which means it can be fed to chickens ducks geese turkey's etc. all poultry. I fed from hatch threw out their lives. I've only ever had one inside duckling and I did add some Brewers yeast to his feed while he was raised by us since I am not sure what all mama ducks show their ducklings to eat to make sure they are getting the right amount of niacin so you may want to pick up some Nutritional yeast or brewers yeast to sprinkle on your ducklings feed just to make sure they are getting all the niacin they need. Any ducklings we have a hatched by their mamas and i have not added anything to their feed just plain ole FR.
