Can Chickens Safely Eat Hammerhead Worms?


Chickens are known for their omnivorous diet, eating a wide range of foods including insects, worms, and even small rodents. However, it is important to ensure that the food provided to them is safe and suitable for their consumption. One question that arises is whether chickens can safely eat hammerhead worms, also known as land planarians.

What are Hammerhead Worms?

Hammerhead worms, or Bipalium, are a type of land planarian that belong to the Geoplanidae family. They have a slender body with a distinct head, which resembles a hammerhead, giving them their name. These worms are predatory and can be found in various habitats, primarily in moist and humid environments.

Feeding Chicken Preferences

Chickens have a natural instinct to forage for food, which includes insects and worms. They particularly enjoy hunting and eating worms, making it an excellent source of protein for them. Insects and worms provide essential nutrients such as proteins, vitamins, and minerals that contribute to the overall health and development of chickens.

Potential Risks

Although chickens generally enjoy eating worms, including earthworms and mealworms, there is limited information available about their consumption of hammerhead worms. Hammerhead worms possess a unique ability to secrete toxins that immobilize their prey. While most predators are affected by this toxin, it is still unclear how chickens would react when consuming these worms.

Proceed with Caution

Given the lack of information on the consumption of hammerhead worms by chickens, it is best to err on the side of caution. If you notice any signs of illness or discomfort in your chickens after they have eaten these worms, it is crucial to seek veterinary assistance immediately. Additionally, it is recommended to consult with poultry experts or your local veterinarian about the safety of feeding hammerhead worms to your flock.

Alternative Food Sources

If you prefer to avoid any potential risks associated with feeding hammerhead worms to your chickens, there are alternative food sources that you can provide. These include commercially available chicken feeds, kitchen scraps (excluding toxic foods for chickens), fresh greens, fruits, and vegetables. These options offer a well-rounded and safe diet for your feathered friends.


The safety of feeding hammerhead worms to chickens remains uncertain. It is advisable to approach this potential food source with caution and monitor the reactions of your flock closely. The welfare and health of your chickens should always be the top priority. When in doubt, consult experts in poultry nutrition and consult with your veterinarian for guidance on the best diet for your chickens.
