Why Eating Watermelon is Good for Ducks (and the Planet)

Apart from offering duck variety in their diet, watermelon contains several nutrients that can improve the duck’s overall health. Since ducks can eat parts of watermelon that humans don’t normally eat, ducks can be very helpful in reducing food waste. More watermelon rinds consumed than discarded benefits both the ducks and the planet as a whole.

Watermelon is a good source of vitamin C and vitamin A, both of which are important for duck health. Increased consumption of vitamin C proved beneficial in increasing egg production in ducks. Vitamin C also helps ducks manage stressful conditions, especially heat stress, and boosts overall immunity.

Vitamin A deficiency can cause various health problems in ducks. Increased levels of vitamin A, on the other hand, can help ducks grow bigger and stronger overall. Eating watermelon as part of a balanced diet can help ducks maintain healthy levels of vitamin A.

Not surprisingly, given its name, watermelon contains about 92% water. Therefore, eating watermelon can help ducks stay well hydrated. This is especially helpful during the hot summer months, when weather conditions can make it difficult for ducks to maintain their hydration status.

How to Safely Feed Watermelon to Ducks


As previously discussed, ducks love to chew on discarded watermelon rinds and seeds. They may find the skin easier to eat if it is cut into smaller pieces. While watermelon seeds are safe for ducks to eat, they should not be overfed or they will have a hard time digesting the excess seeds.

If you decide to offer your duck watermelon as a gift, there are a few different ways to feed it. Obviously, you can cut up and offer the watermelon chunks to the ducks. Be sure to keep an eye on them as they eat them as a small piece of food poses a potential choking hazard to the ducks. Another option for feeding duck watermelon is to puree it in a blender and serve it in the hollowed out half of the watermelon. You can also add pieces of watermelon or other fruit to the mixture.

When feeding your duck watermelon, make sure to only feed fresh fruit, not old or rotten. While ducks can eat a wide variety of foods, rotten or moldy food can make them sick. Be sure to remove any uneaten watermelon out of the duck’s reach before it spoils.

Other Foods Ducks Can Eat (and Few Shouldn’t Eat)
