After a day of swimming in the pond, our ducks enjoyed a special snack of strawberries.
I gave them the end pieces and steams of some strawberries that I had cut up. They loved it!
Here is a bit of information about treats for ducks from Fresh Eggs Daily.
Treats for ducks should be limited to no more than 10% of a duck's daily diet, although greens, such as weeds, cut grass, kale, chards, etc. can be fed in unlimited amounts. Chopped grass and weeds simply added to a tub of water will make your ducks very happy.
All kinds of weeds and grasses will make healthy treats for ducks that they will love.
Ducklings can also eat anything on this list as long as the treat can be cut into very small pieces or is soft or mushy to prevent choking. The sooner you introduce baby ducks to a variety of foods, the more accepting they will be and the more apt to try new treats. I find that ducks in general will be more likely to eat foods that are cut up.
Of course when feeding anything to a duckling or grown duck, be sure they have access to plenty of fresh drinking water and they need grit (coarse dirt, pebbles or stones) to help them digest their food.
Here are some of our ducks' favorite treats to give you some ideas:
Ducks enjoy many different types of fruits, but our ducks' three favorites are strawberries, blueberries and watermelon.
Ducks will eat strawberries whole or sliced, tops and all.
Watermelon can be served cut in half, sliced or in cubes.
I know tomatoes are technically a fruit, but I put them here with our ducks' favorite veggies, along with cucumbers, peas, broccoli and corn.
Cucumbers can be fed sliced, halved or diced, skins and all.
Fresh, frozen or canned (rinse the salt off) peas are fine, however dried peas or beans are toxic.
Corn can be fed raw, cooked or on the cob.
Ducks love broccoli raw or cooked and will eat the florets, leaves and stalks.
Whole grains are better than other grains for ducks.
Brown rice is more nutritious than white rice and should be cooked first.
Ducks love raw or cooked old-fashioned oats.
Favorite proteins include dried or live meal worms, earthworms, slugs, minnows or feeder fish and shrimp shells.
The foods listed below can be hazardous or toxic to your ducks in large enough amounts. They can cause severe health problems or death. If you have given your ducks any of these treats and did not have a bad reaction, then you were lucky. Remember that ducks are prey animals and therefore instinctively hide symptoms of illness and you may not see any problems until a duck dies for no apparent reason, so best to steer clear of anything potentially dangerous.
Some of these foods are only toxic in large amounts, others might not be toxic to all ducks, or only sometimes kill a duck, others can kill or cause health problems after repeated feedings. Bottom line, none are healthy for ducks and therefore should be avoided.
The following foods can be dangerous for ducks:
Crackers or any other salty, sugar-laden or fatty foods are bad for ducks, who gain weight easily. Added weight puts too much strain on their legs and can lead to problems walking. Ducks can also easily die of salt overdoses.
Citrus fruits (lemons, limes, grapefruit, oranges) are thought to interfere with calcium absorption and contribute to thin-shelled eggs. Citrus fruits can also cause acid reflux and stomach pain in ducks.
Bread can not only make your duck overweight if fed in large quantities, but can also lead to impacted crops which can be fatal. In limited amounts, whole grain breads are okay.
Mangoes can make ducks' throats itchy, as it does in some humans. If you do feed your ducks mango, watch them for any reaction. If they seem fine and enjoy it, then it's okay to feed to them.
Spinach interferes with calcium absorption and can reduce the amount absorbed by a duck's body, thereby causing egg binding in females, or soft-shelled eggs. Spinach is extremely nutritious but should be fed in limited amounts only.
Also limit the iceberg lettuce you feed your ducks since it has very little nutritional value and can cause diarrhea in large amounts. Far better choices are leafy greens such as cabbage, kale and collards.
Nuts and large seeds don't digest well and can cause choking or get stuck in the crop since ducks swallow their food whole. If you do feed nuts or seeds to your ducks, they should be ground first. Apple and cherry seeds are toxic so avoid those all together, as are peach and apricot pits.
