I feed mine Purina Flock Raiser. It seems to keep mine quite healthy. I also give a little bit of Scratch Grains which they really don't have to have and a scoop of Layer Pellets. Now that I have my Drakes separated they will not be getting any Layer Pellets but the small amount that is with their feed has never been an issue for any of them. My Mallard Rouen will still get some but not the rest of the boys. My ducklings only get the Flock Raiser and have always done really well on it or on Dumor 22% Duck All Life Stages which I buy sometimes for them. All of my ducks have always been extremely healthy. I have never had to deal with a sick one so I have really been blessed. They have it 24/7 in big covered bowls with water 24/7. They live on sand and in my covered houses they have wood shavings that are replaced periodically.The biggest hurdle on the “best” feed I’ve been trying to sort out is that many are labeled as “layer”, and the instructions specify to not feed it to male birds...
I have not resolved that yet.
Especially because I am allergic to soy and corn, and try to avoid feeding it to my birds that we raise for meat and eggs.
The feed we are currently using is 18% protein. I add (quick) oats to it to cut the protein levels for the ducks.
How much to add depends on the feed, and how many ducks you are managing.
I just buy Quaker quick oats at Costco and estimate how much to add/ watch the “kiddos” and adjust as needed.
I also add brewers yeast tablets to the feed, ground up w a mortar and pestal, that I get at my local feed store. It is labeled for dogs, but the math of the dosage and the approximate weight of the total number of birds you are feeding, is pretty straightforward. The oats and niacin are added to every batch of feed for the ducks.
It’s kind of an art, and kind of a science at the same time![]()
