Are There Any Legal Restrictions on Feeding Mealworms to Chickens?

Fortunately, there are no laws prohibiting chicken owners from feeding mealworms to their flock. Mealworms are not a regulated feed source and can be purchased from pet stores or online retailers or raised at home without issue. As long as you are providing mealworms as a supplement and not the sole diet, feeding them is completely legal. However, always check your local ordinances to ensure there are no restrictions on raising mealworms in your area before starting your own cultivation operation.

Evaluating the Safety of Mealworms for Chicken Consumption

Mealworms are a safe and nutritious food source for chickens. In the wild, chickens naturally consume insects like mealworms as part of their varied diet. The main safety concern is ensuring the mealworms do not contain parasites, bacteria, or toxins.

When purchasing mealworms, opt for reputable, commercial producers to ensure you are getting high-quality, contaminant-free mealworms. If raising your own, maintain good sanitation practices in your mealworm bins to prevent disease. Providing a supplement of fresh fruits and vegetables helps maintain healthy gut flora in the mealworms as well.

As long as sound cultivation and feeding practices are followed, mealworms pose no significant safety risks for chickens. They can be fed freely along with a balanced diet.

What Are the Benefits of Feeding Mealworms to Chickens?

Adding mealworms to a chicken’s diet provides a number of excellent health and production benefits:

  • High in Protein – Mealworms contain 48-60% protein, giving chickens an excellent source of this vital nutrient for growth, egg and feather production.
  • Healthy Fats – Up to 30% of a mealworm’s composition comes from healthy fats like omega-3s and omega-6s. These support skin and feather health.
  • Vitamins & Minerals – Mealworms provide B vitamins, zinc, copper, and more to support immune function and develop strong bones.
  • Natural Behavior – Chickens love foraging for insects. Mealworms allow chickens to engage in natural pecking behavior.
  • Increased Egg Production – The protein-rich punch of mealworms can increase egg production in hens.

When fed as a supplement to a balanced diet, mealworms are a prime source of essential nutrients backyard chickens need to thrive.

What Risks Are Associated With Feeding Mealworms to Chickens?

While mealworms are very healthy for chickens, there are a couple of risks to be aware of:

  • Choking Hazard – Whole mealworms may pose a choking risk, especially for smaller breeds and baby chicks. Chopping up larger mealworms mitigates this.
  • Allergic Reaction – On rare occasions, chickens may have an allergic reaction to mealworms exhibited by facial swelling, scaly skin, diarrhea, or lethargy. Discontinue feeding if any symptoms arise.
  • Nutritional Imbalance – Too many mealworms and not enough balanced feed can lead to nutrient deficiencies long-term. Mealworms should be limited to less than 10% of total feed.
  • Increased Risk of Disease – Mealworms may harbor pathogens like salmonella. Proper raising and cultivation of mealworms reduce this risk significantly.

By chopping mealworms, properly supplementing and sourcing from safe cultivation sources, the risks can be minimized effectively.

What Types of Mealworms are Best for Chickens?

There are three main varieties of mealworms that can be fed to chickens:

  • Live Mealworms – Freshly harvested, living, and wriggling mealworms. Chickens will chase these down as they move.
  • Dried Mealworms – Mealworms are dried and dehydrated to extend shelf-life. Rehydrating restores some wiggle.
  • Mealworm Pupa – The pre-adult life stage. Pupa remain dormant and do not move until maturity.

All three types are nutritious and safe for chickens. Live mealworms encourage foraging behaviors, while dried mealworms are easier to store long-term. Pupa offers a crunchy, pupa-only snack. Mix up worm varieties to give your flock something exciting to peck at.

Are Raw Mealworms a Viable Option?

Absolutely! Raw, live mealworms are a great way to feed chickens and allow them to exhibit natural foraging instincts. In fact, raw mealworms may even have slightly higher vitamin content than processed options.

…live mealworms are a great way to feed chickens and allow them to exhibit natural foraging instincts.

The key is sourcing contamination-free mealworms and providing them in moderation alongside balanced feed. This ensures raw mealworms pose a very low risk of transmitting bacteria or parasites.

Let your flock scratch, peck, and gobble up raw mealworms to their heart’s content for an interactive, nutritious dietary supplement.

Should Mealworms Be Cooked Before Feeding?

Cooking mealworms is not necessary and provides no significant benefits. Mealworms do not contain any compounds or proteins that need to be denatured by cooking.

In fact, cooking may reduce some of the beneficial nutrient content. Cooked mealworms also lose their wiggle, which chickens love when foraging.

Feed chickens mealworms raw or dried for the optimal nutritional punch and to allow chickens to engage in natural foraging behaviors. Skip the cooking and let them enjoy their wriggly goodness!

How Much Can Chickens Safely Eat in Mealworms?

Moderation is key when feeding mealworms. About 1-5% of a chicken’s total daily feed intake can come from mealworms without causing issues. Free-choice feeding is not recommended.

To put this in perspective, for every 1 lb of balanced feed provided, chickens can eat 1-5 oz of mealworms as well. Larger breeds and older chickens are toward the upper end of the range, and younger and smaller chickens are on the lower end.


Spread the mealworms throughout the day and mix them into feed or offer them separately as a treat. This prevents chickens from overindulging and maintains a balanced nutritional profile long-term.

Feeding Techniques to Maximize Enjoyment and Safety

Here are some top tips for feeding mealworms successfully:

  • Chop larger mealworms into bite-sized pieces to reduce choking risk.
  • Mix dried mealworms into feed for an easier, mess-free option.
  • Broadcast live mealworms across the run to encourage natural foraging behavior.
  • Place mealworms in a deep pan of bedding or hide around run to stimulate pecking.
  • Hand-feed a few mealworms per chicken as an interactive treat.
  • Ration mealworms and do not feed free choice.

With some creativity and proper rationing, you can provide your flock with a fun, engaging source of nutrition they’ll love.

How Often Should Mealworms Be Given?

For optimal health benefits without overdoing it, mealworms can be provided:

  • Once daily as a treat ration.
  • Every other day, mixed into feed.
  • 3-4 times per week broadcast in the run for foraging.

Avoid feeding consecutive days in a row, as mealworms are rich and chickens may overeat if given free access. Mix up when and how often worms are provided week to week for the best results.

Can Baby Chicks Enjoy Mini-Mealworms Too?

Baby chicks can safely enjoy tiny mealworm treats in moderation. The key is chopping or grinding the worms into tiny, chick-sized bites first. Whole mealworms are a major choking hazard for baby birds.

Chicks can be offered chick crumb-sized mealworm pieces:

  • In their feed bowls mixed into crumbles.
  • In a shallow treat dish for pecking.
  • Sprinkled in brooder bedding for foraging fun.

Start with just a few bits per chick and gradually increase portion sizes as they grow. Avoid free-choice feeding to prevent overconsumption by greedy chicks. With proper preparation and portioning, even little peepers can get in on the worm gobbling action!

Frequently Asked Questions

Are mealworms good for chickens?

Yes, mealworms can be a nutritious addition to a chicken’s diet. They are rich in protein, which is essential for feather growth, egg production, and overall muscle development in chickens. However, it’s important to offer mealworms as a treat and not as a primary food source. A balanced and complete chicken feed provides the necessary nutrients, and mealworms should complement, not replace their regular diet.

Can I give my chickens too many mealworms?

No, chickens should not have too many mealworms. While mealworms are a healthy treat, overfeeding can lead to an imbalanced diet, as they are high in fat. Excessive consumption may contribute to obesity and other health issues in chickens. It’s advisable to limit mealworm treats and ensure the majority of their diet comes from a nutritionally complete chicken feed.

Are dried mealworms safe for chickens?

Dried mealworms are generally safe for chickens when offered in moderation. It’s crucial to source high-quality, additive-free mealworms to avoid potential contaminants.
