Mealworms for Chickens and Turkeys: Benefits, Feeding Amounts and Safety

Quick answer: Chickens and turkeys can eat mealworms, but mealworms belong in the treat portion of their diet. They provide protein and, particularly when offered live, give birds something interesting to chase and peck. They do not replace complete poultry feed, calcium, grit, or an age-appropriate starter ration.

If you are wondering whether mealworms are good for chickens, the honest answer is yes, within a limited role. Their clearest benefits are as a protein-rich treat, a useful training reward, and a way to encourage natural foraging behavior.

Are Mealworms Good for Chickens?

Yes. Mealworms can be a useful addition to a chicken’s treat rotation, provided the flock’s regular feed remains the foundation of the diet.

Yellow mealworm larvae contain approximately 40.2% to 63.3% protein on a dry-matter basis, depending partly on what they were raised on. (1) The words “dry-matter basis” matter here. Water is removed before the percentage is calculated, so this range should not be read as the protein percentage of a handful of live mealworms. Moisture, rearing substrate, development stage, and processing can all change the final nutrient profile.

Chickens naturally eat insects, but they still need prepared feed balanced for their age and purpose. Mealworms cannot provide the planned balance of protein, energy, calcium, phosphorus, vitamins, and other nutrients found in a complete ration.

Benefits of Mealworms for Chickens

A protein-rich treat during demanding periods

Protein supports body maintenance, egg production, and the growth of new feathers. This makes mealworms a reasonable protein-rich treat during a molt, when hens are replacing feathers and may be less interested in their usual routine.

That does not mean mealworms will make feathers regrow faster or improve egg quality by themselves. If a hen’s main ration is poorly balanced, adding mealworms will not reliably correct the underlying problem.

Foraging and food-based enrichment

Live mealworms move, which gives chickens a reason to watch, chase, peck, and search. Research with laying hens found that the birds regarded live mealworms as a valuable reward and were willing to work for access to them even when fully fed. (2)

This supports using mealworms for food-based enrichment and training. It does not establish that mealworms prevent stress or resolve harmful flock behavior. Housing, space, flock dynamics, nutrition, lighting, and health still need to be assessed when birds show persistent feather pecking or aggression.

A practical training reward

A few mealworms can help teach birds to return to the coop, approach a familiar container, or stay occupied while you inspect an individual bird. Reserving them for these moments can be more useful than adding a large serving to the feeder.

How Many Mealworms Should Chickens Eat?

There is no reliable universal number of mealworms per chicken. A large hen and a small bantam do not have identical needs, and live mealworms contain considerably more water than dried ones.

UF/IFAS Extension recommends keeping treats below 10% of a chicken’s overall diet so they do not displace balanced feed. (3) That limit includes every treat offered during the day, rather than 10% mealworms followed by additional scratch grains, fruit, or table scraps.

The 10% figure is a ceiling, not a daily target. Birds do not need mealworms every day. Offer complete feed first, then provide a modest portion that the flock can finish promptly.

Can Chicks Eat Mealworms?

Chicks can eat insects, but mealworms should not be described as an essential part of rearing young birds. Complete chick starter is designed to supply the protein, vitamins, minerals, and amino acids required during early growth.

There is no single week that applies to every flock. A cautious approach is to wait until chicks are eating starter reliably, introduce only a very small, appropriately sized portion, and keep starter feed freely available. The University of Arizona Cooperative Extension advises providing grit in a separate container whenever chicks receive anything other than chick starter. (4)

Mealworms should never be used to replace starter feed or to treat leg weakness, slow growth, or a suspected vitamin deficiency. Those problems require a review of the complete diet and, when necessary, veterinary guidance.

Can Turkeys Eat Mealworms?

Adult turkeys can also have mealworms as an occasional treat or training reward. The same basic rule applies: mealworms should complement a suitable turkey ration rather than compete with it.

Extra caution is needed with poults because their starter feed is formulated around the nutritional demands of early growth. A handful of mealworms may contain plenty of protein, but protein content alone does not make something a complete starter feed. Mealworms should remain a small extra rather than replacing any part of the poult’s regular ration.

Live vs. Dried Mealworms

Live and dried mealworms can both be fed in moderation. One is not automatically healthier than the other. The better choice depends on whether you prioritize movement and enrichment or storage and convenience.

Whichever form you choose, use mealworms raised or sold for animal feeding and keep their housing, storage container, and feeding area clean. Labels such as live, dried, domestic, or imported do not by themselves establish whether a product will improve or reduce egg production.

How to Feed Mealworms for Enrichment

1. Let birds eat their regular feed first. Mealworms should not become the reason they ignore a balanced ration.
2. Use a clean feeding area. A shallow tray or clean section of the run makes it easier to see how much the flock consumes.
3. Spread the serving across several spots. This gives more birds a chance to participate instead of allowing one dominant hen or turkey to claim everything.
4. Reserve a few for training. Use them to teach a recall cue, encourage birds into the coop, or keep them occupied during routine checks.
5. Count mealworms among all daily treats. Scratch, fruit, vegetables, and other extras still contribute to the same treat allowance.

Frequently Asked Questions

Can chickens eat mealworms every day?

They can receive a small portion regularly, but they do not need mealworms every day. Frequency matters less than the total amount. Keep mealworms and all other treats combined below 10% of the diet.

Do mealworms help chickens during molt?

Mealworms provide protein, and protein is required for feather growth. A modest serving can therefore be a useful treat during molt. However, mealworms have not been shown to guarantee faster feather regrowth. Continue feeding a complete ration suited to the flock.

Are mealworms good for laying hens?

Mealworms can be fed to laying hens as a treat, but they should not be expected to increase egg numbers or improve egg quality on their own. Balanced layer feed, appropriate calcium, water, health, age, lighting, and environmental conditions all influence laying performance.

Can mealworms replace chicken or turkey feed?

No. Mealworms contain useful nutrients but are not a complete poultry ration. Chickens and turkeys still require feed formulated for their species, age, and production stage.

Can chickens eat dried mealworms?

Yes. Dried mealworms can be offered in moderation. Because drying removes water, they are more concentrated by weight than live mealworms, so avoid pouring an unrestricted amount into the feeder.

Mealworms earn their place in a flock’s routine because birds value them and keepers can use them in practical ways. Keep that role modest: complete feed first, mealworms second.
