How Ducks Digest Grass? They Have Enzymes!
Ducks have this pouchy thing called a cecum right, where their small and big intestines meet up. Bacteria and protozoa inside the cecum have enzymes that can break down the tough stuff in the grass, like cellulose and hemicellulose. These are a kind of plant fibers.
Through fermentation, these things team up to turn plant stuff into simpler, easier-to-digest stuff.

Do Ducks Like Grass? Not Sure
I have always been saying that it’s really difficult to say ducks like something or not. Because they literally go crazy over whatever is given to them. The thing is, they eat it. And the grass won’t do any harm. Instead, it provides some essential nutrients like protein, fiber, fat, and calcium.
So, no matter whether they like it or not, grasses are harmless and fine to consume.
Can Baby Ducks Eat Grasses? Only Clean and Pesticide-Free Grass

Yes, baby ducks can eat grasses as well. In fact, it has been suggested to give ducks grass from an earlier age. Because if they grow up without it, they may not be interested in it later. But, still, you should not feed grass to your baby ducks. Here’s why.
If you want them to get used to it, give them after three weeks. Because, before that, they’ve got a very sensitive digestive system. Only adequate nutrition should be provided to them at that time, like duck feed rich in calcium and protein. Hence, no grass for baby ducks.
Anyway, if you still want to give it to these adorable babies, no issues! Just make sure these are free from pesticides and clean.
My Ducks Eat Grass Every Day: Will It Hamper?
Your ducks eating grass every day is okay, but you should be aware of some important things. There are both good and not-so-good aspects of ducks eating grass every day.
Positively seeing ducks grazing on grass is natural and sort of like what they’d do in the wild. But that doesn’t mean they should eat grass every single day. Too much grass can mess with their nutrition and might cause tummy problems because it’s full of plant stuff.
In addition, I’m pretty sure you already know that not all grass is safe. Some grass might have pesticides or other stuff that could be bad for your ducks if they consume it. So, it’s alright that they like a bit of grass, just make sure to watch out.

Grass in Different Forms – Can Ducks Eat All of These?
Grass can be found in different forms. Can ducks eat all of them? No, they can’t. Which forms of grass aren’t suitable for ducks? Well, I’ve made a list myself. Let’s have a look at the list and know which form of grass is for ducks and which isn’t.
- Fresh Grass: Fresh grass is fine for ducks. Specially mowed grass. These are soft and easier to digest for ducks.
- Dried Grass: Well, dry stalks may not be a good deal for ducks. As it’s a bit hard, it can cause choking trouble. However, you may see ducks eating dried grasses in the countryside. So, dried grass won’t cause any trouble until it is too hard to digest and not contaminated.
- Hay: Same thing as dried grass. Hay is quite nutritious as well. It can be a good resource for fiber and other essential nutrients.
- Straw: Straw is also a part of dried grass. But straw may not be a good addition to ducks. But still, if you give them, they may eat it due to their foraging behavior.
Are Grasses Carry A Skyhigh Nutritional Value? Not Really

No, grasses do not have a massive nutritional value like feeding dandelions to ducks. It’s not sky-high, either. See, eating grass is only a part of their foraging interest. So, let them be allowed to show their natural behavior. They look cute when they do so.
Here are the nutrients grass provides for ducks:
- Fiber: 4.6g
- Protein: 2.2g
- Carbohydrates: 3.3g
- Calcium: 30mg
- Phosphorus: 20mg
- Vitamin A: 1000 IU
See, the grass isn’t so high in nutrients ducks need. But they aren’t too harmful either. All in all, they’re good for ducks, and that’s it. There’s nothing significant to call it sky high, which means it isn’t something to consider a really important part of their diet.
However, herbs are a crucial part of ducks’ diet. In case you don’t know, you may read our article on herbs for ducks on our website.
4 Key Benefits of Feeding Grass

Let’s have a look at the four prime benefits that grass provides.
1. Digestive Health
The grass is a good source of fiber. Dietary fibers help improve digestion by promoting gut function and preventing other digestive issues.
2. Enhances Foraging Behaviors
Ducks are foragers in general. The grass is the most available food source that backyard ducks will find in their foraging. So, foraging for grass will help them engage in their natural feeding behavior.
3. Natural Vitamin Intake
Grass often contains essential vitamins, such as vitamins A and K. These vitamins play crucial roles in maintaining healthy vision, blood clotting, and overall immune function in ducks.
4. Better Feather Health
Ducks like spending time preening and grooming their feathers. Roaming around and consuming grass may potentially bring benefits to improving feather health. Fibers from the grass can help remove dirt and debris from their plumage.
Can Grasses be Toxic To Ducks? Can Even Be Deadly!
Yes, some grasses can be toxic to ducks. These toxic grasses may have harmful compounds such as phalaris spp. (tryptamine and carboline alkaloids), sorghums (cyanogenic glycosides). Some tropical grasses contain oxalates and saponins.
Here comes the most fatal part, some grasses can even be deadly due to carrying cyanide. So, yes, these toxic grasses can potentially lead your ducks to even death. These grasses can cause digestive issues, liver problems, or other health concerns in ducks. So, you have to be aware of this toxic grass.
How do we recognize toxic grass? Sadly, there’s no such way to recognize those. If you’re even a little worried that your ducks might’ve chewed on some toxic greens, your best bet is to have a chat with a vet.
Now, Pay Attention: Ducks are not immune to poor plant choices. If they’ve had a bad experience with grass, they may become lethargic, lose their appetite, or have diarrhea. So, if you see any of these signs, it’s your duck alarm notifying you something’s wrong.

Bottom Line
Ducks eating grass is just a part of their roaming interest. No matter whether they like it or not, they eat it. However, always look for their behavior pattern. If they show a lack of appetite or lethargicness, contact a veterinarian. It may be because of consuming toxic grass around your house.
Finally, don’t worry if you see your ducks eating grass. It’s beneficial, too. I suggest not to consider it an essential part of their diet. Let them eat if they find it a tasty treat for them.
