Feeding Chickens Unripe Watermelon: Is It Safe?


Watermelon is a refreshing summer fruit loved by many, and its juicy red flesh is a common treat for humans during hot days. But have you ever wondered if you can share this delicious fruit with your backyard chickens? More specifically, is it safe to feed them unripe watermelon? In this article, we will explore this question and provide you with some insights.

The Nutritional Value of Watermelon for Chickens

Watermelon is a rich source of various nutrients that can benefit chickens. It contains vitamins A, B6, and C, which contribute to their overall health and immune system. Additionally, watermelon is low in fat and calories, making it a healthy treat that won’t negatively impact their weight.

Is Feeding Unripe Watermelon Safe?

Unripe watermelon, on the other hand, poses some potential risks for chickens. The main concern is the high levels of cucurbitacin, a compound found in unripe watermelon and other members of the cucurbit family, such as cucumbers and squashes.

Cucurbitacin gives unripe watermelon its bitter taste and acts as a natural deterrent to herbivores. While it is harmless to humans in small amounts, chickens are particularly sensitive to this compound. Ingesting excessive amounts of cucurbitacin can lead to digestive issues, such as diarrhea or indigestion, and even poisoning in severe cases.

Precautions to Take

If you still want to feed watermelon to your chickens, it is advisable to choose ripe watermelons instead. Ripe watermelons have lower cucurbitacin levels and are safe for consumption by both humans and animals. You can check if a watermelon is ripe by examining its color (it should be a deep, vibrant red), tapping it (a hollow sound indicates ripeness), and observing the condition of its skin (it should be firm and free of blemishes).

It’s essential to remember that watermelon should never replace a balanced diet for chickens. Treats, including ripe watermelon, should be given in moderation and as part of a well-rounded nutritional plan that includes a diverse range of foods suitable for the chickens’ needs.


While watermelon can be a tasty and healthy treat for chickens, it is vital to provide them only with ripe watermelons. Feeding unripe watermelon to chickens can pose potential health risks due to its high cucurbitacin content. By taking precautions and ensuring a balanced diet, you can safely treat your chickens to this juicy fruit during the summer months.
