What Should I Feed My Ducks?

Feeding ducks is slightly different than feeding chickens as their dietary requirements are not quite the same. However, ducks can eat chicken feed, as long as it is un-medicated.

Ducks require nearly twice as much Niacin (vitamin B3) in their diets than chickens do. Without having enough niacin, ducks end up with leg and joint issues and possibly leading to death.

I found feed specifically for ducks hard to find locally. I personally started with chick starter and brewers yeast.

Water + Grit

Ducks need water in order to swallow their food. As a result, If they do not have access to water, while eating, they can choke.

Grit is just as important, once they have started eating any food that is not duck/ chick feed. Grit is just small rocks, course dirt, or sand that they swallow to help aid in digestion. Since they do not chew, ducks use their gizzard to grind up the food before continuing through their digestive system.

Free range ducks do not require grit. They eat it naturally while they are foraging. If your ducks are kept in a pen they will require you to give them a constant supply of grit.

0-3 Weeks Old

Duck starter crumbles (or chicken starter crumbles) with 20% protein.

I’ve heard of successes within a 1-2% range, up or down. However, 20% seems to be the most popular.

If you choose to use chicken starter you need to supplement with Niacin

I have read some people use Niacin pills from a pharmacy and mix that with their food or water. I found it quite confusing on how much to give them.

Ducks also spill lots of water as they drink. So, they may not be ingesting enough of the supplement.

I use Brewer’s Yeast (can also use nutritional yeast flakes). I got it from the farm store. It came in bulk so I buy a big bag at a time, depending on how many ducklings we have.

Mix 1 tbsp. Brewer’s Yeast with 1 cup chick feed. I pour it on top of their food so they ingest as much as possible before it ends up on the bottom.

3-20 Weeks Old

Your ducklings can now move onto Grower Feed with a lower protein. Ours is 17-19% protein chick grower.

Continue with adding the same amount of Niacin.

20 Weeks and Older

They can now be fed layer or breeder food suitable for ducks and chickens with 16% protein.

For drakes and non-laying females you want to give them a maintenance diet with about 14% protein.

If you have a mix of various ages and types of poultry all together you can get All Flock Feed. It covers the nutrients of requirements of layers, broilers, turkeys, geese, ducks and pheasants.

 Protein %Additional Niacin
0-3 weeks20% Starter1tbsp/1cup
3-20 weeks18% Growers1tbsp/1cup
20+ weeks – laying ducks16% Layer or BreederN/A
20+ weeks – drakes and non-laying females14% Maintenance dietN/A

Broiler ducks (raised for meat) can be fed a feed with 20% protein as they grow rapidly and will have a short lifespan.

There is a bit of controversy over when ducks should switch to a laying feed.

Some people say it shouldn’t be done until they lay their first egg.

Other people say as it should be done by age. However, the age ranges from 16 weeks up to 24 weeks.

I have also heard it be recommended that if you have any males, or ducks that are not laying eggs, they should be given all maintenance feed (or an all flock feed).

In addition to, a bowl of oyster shell offered in a separate dish.

The laying females that need the additional calcium will eat the oyster shell and the males will leave it alone. This way the males and other ducks that don’t need the calcium don’t end up with health issues caused by too much calcium.

It’s one of those things where some people have had success with a certain way and other people have not. For me personally I will be offering a maintenance feed and crushed oyster shell once they lay their first egg.

Snacks to Feed Ducks

Ducks can eat a lot of fresh food when it’s been prepared properly.

Not only does it make eating time a bit more fun for them it adds nutrition to the ducks and their eggs.

According to HGTV, “Treats for your ducks should be limited to no more than 10% of their daily diet, although ‘green’ treats, such as weeds, cut grass, lettuce, chard, etc. can be fed in unlimited amounts.”

Ducks don’t chew their food. They swallow everything whole. So it does need to be offered in sizes small enough for them to swallow whole.

You can also offer them soft foods. They should be able to tear pieces off or squish it with their beak. I like to compare them to babies who are just starting to eat solids.

When in doubt, cut the food smaller.

  • Apples – no seeds
  • Apricots – no pit
  • Asparagus – Cooked
  • Bananas
  • Beans –cooked or fresh, No raw
  • Beets – cooked or grated
  • Berries

  • Cucumber
  • Feeder fish/ minnows
  • Fresh Herbs
  • Grapes – cut in half, do not feed whole grapes
  • Kale
  • Lettuce
  • Meat or fish – cooked
  • Lobster
  • Mealworms – dried or live its a number one favourite treat

  • Millet
  • Oats – cooked or uncooked. No sugar or flavoured
  • Parsnips – cooked or grated
  • Pasta – cooked and only small amounts sparingly
  • Pear – no seeds

Sprouts are also a great snack for your ducks. They are easy to grow cost effective. They are highly nutritious and ducks love them.

What Not To Feed Ducks

There is a long list of things ducks can eat.

But, there is also a longer list of food that ducks should not eat.

These include but are not limited to:

  • Alcohol
  • Avocado
  • Bread – crackers, chips etc.
  • Caffeine
  • Canned Foods – too much sodium
  • Carbonated Beverages
  • Citrus fruits – oranges, lemons, limes, grapefruits
  • Chocolate
  • Dried Beans, Noodles, or Rice
  • Iceberg Lettuce – no nutritional value, can cause diarrhea
  • Nuts and seeds – easy to choke on, only serve ground nuts, best to avoid
  • Onions
  • Pepper plant – fruit is okay, avoid giving the core with all the seeds
  • Popcorn
  • White Potatoes – vegetable and the plant
  • Processed and sugary foods
  • Rhubarb
  • Spinach – interferes with calcium absorption, only in very small amounts or avoid all together
  • Tomato plants – only the fruit itself is okay to give, no green tomatoes

It is fine to give ducks our food scraps and bruised/ mushy foods that we do not want to eat. But, they should not be given foods that have spoiled and gone moldy.

Plants That are Not Safe

I have searched the internet and compiled a list of all the plants that I found listed as toxic to ducks, chickens, and other birds.

If ducks have enough edible plants to forage around they will leave the toxic plants alone. They tend to be quite bitter and after one taste the ducks know to stay away from it.

On top of the long list of things ducks are not allowed, it also includes herbicides, pesticides, rodenticides, and some fertilizers. It is important that you do not give your ducks, or allow them access to, any plants that have been treated. If you are trying to get rid of pests and weeds from the garden try a more natural route.

  1. How is rice not safe to feed ducks? I came from a country wherein we feed left over rice to the ducks since the olden days lol

  2. Gogo Theophanopoulou

    Hello from Southern Peloponnese, Greece. Just like you we are a couple of retired computer programmers that lived all our life in Athens. No idea about rural area but my hubby had studied agriculture in the University but never worked in this area. We bought a small grove very close to the sea and among other things we have muscovy and Peking ducks. It is impossible to find special food for them and we found a good quality of chicken food with no medication close to the needs of ducks. I haven’t solved the niacin problem yet. Did you buy dried brewer’s yest or fresh? We have now 7 ducklings 1 month old. I have tried to dissolve fresh yest in the water but they will not drink it. The peas are of the same quality dried or frozen. If yes, what is the amount of daily consumption. By the way I love your duck photos.

    1. I actually found brewers yeast at a local farm store. They come in small buckets of powder, located in the horse section. I have recently heard that some people use nutritional yeast as well. Though I dont know if it is the same ratios to feed. I dont add it to water as they spill and splash way too much I have no way to see how much they actually ingest. When my ducks were little I defrosted and mashed their frozen peas and served in a bowl of water. I dont measure how much, just a normal sized bowl filled with peas and water. I wish you luck. Let me know if you have any more questions!
