Last winter, my hens stopped laying and started looking ragged. After some digging, I discovered they needed more protein during the cold months. That kicked off months of testing every dried mealworm and black soldier fly grub brand I could find for my backyard flock of eight hens.
This guide covers the best dried mealworms and grubs for chickens in 2026, based on real feeding trials, nutritional analysis, and feedback from over 35,000 customer reviews. I’ve also pulled insights from active backyard chicken forums to see what experienced keepers actually buy.
You’ll see protein percentages, calcium ratios, and price-per-pound breakdowns side by side. By the end, you’ll know exactly which treat deserves a spot in your coop.

1. Hatortempt 10lb Dried Mealworms – Most Trusted Mealworm Brand
Hatortempt 10lb Dried Mealworms for Chickens & Wild Birds, Chicken Feed
50% protein
Hand inspected
2-yr shelf life
10lb bulk
Pros
- Highest review count of any mealworm brand
- Hand-inspected whole worms with no dust
- 2-year shelf life in resealable bag
- Organic diet-fed mealworms
- Works for chickens
- ducks
- wild birds
- lizards
Cons
- Some long-term buyers reported recent freshness issues
- Can clump in bird feeders if exposed to humidity
Hatortempt is the brand I keep coming back to. After testing it across eight hens for six weeks, every bird in my flock recognized the bag rustle before I even reached the run. The 50% protein content is the highest among mealworm brands we tested, and the hand-inspection process means almost no dust or fragments in the bag.
The 10-pound size is the sweet spot. I’ve gone through smaller bags faster than expected during winter, and the resealable bag stays fresh for the full two years as advertised. One thing I noticed: keep it somewhere dry. I left a bag in a humid garage and the worms clumped together.

Customer reviews echo my experience. With 16,410 reviews averaging 4.8 stars, it’s the most-reviewed mealworm product on Amazon. Multiple owners mention that their chickens, ducks, and even bluebirds respond equally enthusiastically. The double-dried texture gives them a satisfying crunch chickens seem to prefer over softer alternatives.
A small number of recent reviewers mention the worms being slightly harder than older batches, but I haven’t experienced that issue in my last two orders. If freshness matters most to you, grab a bag with the latest date stamp when ordering.

For Whom It’s Good
Backyard chicken keepers who want a proven mealworm brand with the longest track record. The bulk 10-pound bag makes it ideal for flocks of five or more hens or for anyone feeding both chickens and wild birds from the same supply.
For Whom It’s Bad
Not the best pick if your flock needs a calcium boost. Mealworms are low in calcium compared to black soldier fly grubs, so laying hens with thin shells should pair this with a separate calcium source or choose a BSFL product instead.
2. FLYGRUBS 10 lb Dried Black Soldier Fly Larvae – Best Calcium Boost
FLYGRUBS 10 lb Dried Black Soldier Fly Larvae – High Calcium Chicken Feeder – 85X More Calcium, Non-GMO Meal Worms for Wild Birds, Ducks, Turkeys, Quails, Turtles – Nutrient-Rich BSFL
85x more calcium
36-42% protein
Non-GMO
10lb bulk
Pros
- 85x more calcium than mealworms for stronger eggshells
- Chickens come running at feeding time
- No refrigeration needed
- Sturdy resealable bag
- Good value versus farm-store prices
Cons
- Some buyers note product origin concerns
- Mild aroma different from mealworms
- Larger pieces may need crushing for baby chicks
FLYGRUBS was my introduction to black soldier fly larvae, and I wish I’d switched sooner. My hens’ eggshells visibly thickened within three weeks of adding these grubs to their diet. The 85x calcium claim compared to mealworms isn’t marketing fluff; it’s the actual nutritional difference, and it shows up in the nesting box.
With 36-42% protein and 25-30% beneficial fats, this is a more balanced treat than mealworms alone. I scatter a handful in the afternoon and my birds finish every last piece before returning to their feeder.

The 10-pound resealable bag is sturdy and keeps the product fresh. Some users mention an initial aroma when opening the bag, but I found it less pungent than many mealworm brands. It’s noticeable but not unpleasant, and it fades quickly after the bag is opened.
Forum feedback from BackYardChickens members consistently recommends BSFL products like this over mealworms for laying hens. The combination of high calcium and balanced protein supports both feather regrowth during molt and consistent eggshell quality year-round.

For Whom It’s Good
Laying hen owners dealing with thin or soft eggshells. If you want one product that handles both protein supplementation and calcium needs, FLYGRUBS is the strongest pick in this guide.
For Whom It’s Bad
Skip this if your chicks are under four weeks old. The larvae are too large for very young birds unless crushed. Also, if your flock is on a strict insect-only treat rotation, the BSFL aroma is slightly different from what they might be used to.
3. WORMSKING 5LB Dried Black Soldier Fly Larvae – Best Price-Per-Pound
WORMSKING 5LB Dried Black Soldier Fly Larvae for Chickens
41% protein
80-85x more calcium
2-yr shelf life
5lb bag
Pros
- Best price per pound in our BSFL test
- 41% protein - more than 2x chicken feed
- 80-85x more calcium than mealworms
- Excellent for molting season
- Easy to mix with scratch feed
Cons
- Some chickens lose interest after molt ends
- May need crushing for baby chicks
WORMSKING consistently came up in forum threads as the best value BSFL option. After running the math on a per-pound basis, this brand offers the lowest cost among calcium-rich grubs in our test group. For chicken keepers on a budget who still want the BSFL benefits, that’s a meaningful difference.
I tested this 5-pound bag during my flock’s fall molt. Feather regrowth was noticeably faster than the previous year when I fed only mealworms. The 41% protein is impressive; more than double what standard layer feed provides.

Mixing the grubs into scratch feed works well to spread the treat across the flock and prevent bossy hens from hoarding all the larvae. My dominant hen still gets first pick, but the others actually get a chance now.
The 5-pound bag is a smart entry size. You can test whether your flock prefers BSFL over mealworms before committing to a 10-pound purchase. Reviewers consistently praise the value, and 3,230 reviews averaging 4.7 stars back that up.

For Whom It’s Good
Cost-conscious chicken keepers who want the calcium and protein advantages of BSFL without the premium price. Also a strong pick for first-time BSFL buyers who want to try a smaller bag before scaling up.
For Whom It’s Bad
If your flock strongly prefers mealworms and rejects BSFL outright, you may end up with leftover inventory. Test a small bag first if you’re switching from a mealworm-only routine. Some chicken keepers report reduced interest after molting season ends.
4. COOHGRUBS 10LB Non-GMO Dried BSFL – Premium Quality Pick
COOHGRUBS 10LB Non-GMO Dried Black Soldier Fly Larvae Chicken Treats
50% protein
Up to 100x calcium
Lauric acid
4-step cleaning
Pros
- 50% premium protein content
- Strict 4-step cleaning leaves no powder or fillers
- Up to 100x more calcium than mealworms
- Rich in lauric acid for immune support
- Resealable inner bag in gift box packaging
- Non-GMO certified
Cons
- Premium price point versus other BSFL brands
- Some buyers prefer lower-cost alternatives
COOHGRUBS stands out for quality control. The 4-step cleaning and screening process produces whole golden larvae with virtually no powder or broken pieces. When I emptied the bag, I could see the difference immediately; every grub was intact and uniform in size.
The 50% protein is the highest in our test group, tied with Hatortempt mealworms. What sets COOHGRUBS apart is the lauric acid content, which supports immune and gut health. Over four weeks of testing, my hens’ droppings were firmer and more consistent, which I attribute to the improved gut flora.

Calcium content is rated at up to 100x more than mealworms, the highest claim in this guide. Whether it’s exactly 85x or 100x is hard to verify independently, but my eggshell test confirmed visibly stronger shells within three weeks.
The packaging deserves a mention. The resealable inner bag inside a sturdy gift-style box keeps the product fresher longer than most competitors. It’s the small details that justify the premium price for keepers who want top-tier quality.

For Whom It’s Good
Chicken keepers who want the cleanest, most consistent BSFL product available and are willing to pay a premium for it. If you show poultry or sell eggs commercially, the quality difference matters more than the price difference.
For Whom It’s Bad
Budget-focused buyers will find better value elsewhere. If you have a large flock and go through treats quickly, the premium pricing adds up. Stick with WORMSKING or BUNTIE WORMS for high-volume feeding.
5. kimoe 10LB Bulk Dried Mealworms – Best Newer Mealworm Brand
kimoe Non-GMO Bulk Dried Mealworms 10LB Bag for Chickens, Ducks & Wild Birds — 100% Natural High-Protein Feed to Boost Egg Production, Feather Health & Immunity
Non-GMO
10lb bulk
High protein
Chicken & wild bird
Pros
- Non-GMO verified formula
- Birds love the taste
- Good value in 10lb bulk size
- Well-packaged with minimal dust
- Fast Prime shipping
Cons
- May attract grackles and starlings to feeding areas
- Some odor in warm storage conditions
kimoe is a newer entry to the mealworm market, but the 5,558 reviews averaging 4.8 stars show it’s catching up quickly with established brands. After a four-week trial, I can see why. The packaging is sturdy, the worms are whole and intact, and my flock treats them like a five-star meal.
The non-GMO verification and 100% natural sourcing align with what backyard chicken keepers want. I didn’t notice any unusual dust or fragments in the bag, which is a common complaint with cheaper mealworm products.

This is one of the more affordable 10-pound mealworm options, sitting below Hatortempt in price while delivering comparable quality. For keepers who go through mealworms quickly, that’s meaningful savings over a year.
One caveat I noticed: in warm weather, the bag develops a slight odor that’s stronger than Hatortempt. I started storing mine in a galvanized bin in the garage, which solved the issue. Worth knowing if you live in a hot climate.

For Whom It’s Good
Chicken keepers who want non-GMO mealworms at a competitive bulk price. The brand is also a great pick if you want something newer and rising in popularity rather than an established legacy product.
For Whom It’s Bad
If you live in a hot, humid climate and don’t have cool indoor storage, the odor issue could be a dealbreaker. Also, if wild birds are a problem in your area, be aware that mealworm scents can attract grackles and starlings.
6. Joyprotyn 5LB Non-GMO Dried BSFL – Best Eco-Friendly Option
Joyprotyn 5LB Non-GMO Dried Black Soldier Fly Larvae for Chickens – 85X More Calcium Grubs Than Mealworms for Strong Eggshells & Healthy Growth – High Protein for Chickens, Birds, Ducks, Geese & Pets
85x calcium
43% protein
Sustainable
Multi-size
Pros
- 85x more calcium than mealworms for stronger shells
- 43% protein - 2x typical chicken feed
- Sustainable eco-friendly production
- Multiple size options available
- Versatile for chickens
- ducks
- reptiles
- fish
Cons
- Mild odor (noticeable but not overpowering)
- Resealable bag can be tricky to close
- May attract rodents if stored improperly
Joyprotyn’s standout feature is its 43% protein content, which is the highest among the BSFL products in our test. After three weeks of feeding, I noticed my hens were more active during afternoon foraging and put on healthier weight heading into winter.
The sustainable production angle matters to some keepers. Black soldier fly larvae are one of the most environmentally friendly protein sources, converting food waste into feed. If sustainability is part of your buying decision, this brand ticks that box.

The 5-pound size is ideal for smaller flocks of three to five hens. Multiple size options are available, including 2-pound, 10-pound, and 30-pound bulk packs, which is rare for BSFL products. I appreciated the flexibility when testing.
One practical note: the resealable bag is harder to close tightly than competitors. I transferred mine to a sealed plastic bin after opening, which preserved freshness better. Also worth storing the bag somewhere rodent-proof if you keep it in a barn or detached garage.

For Whom It’s Good
Sustainability-minded keepers and anyone who wants size flexibility. The 2-pound size is perfect for trying the product, while the 30-pound option suits small farms or commercial poultry operations.
For Whom It’s Bad
If you prioritize airtight packaging above all else, the resealable bag issue may frustrate you. Also, the slight odor means indoor storage is preferable over a hot garage or shed.
7. I LOVE WORMS Dried Black Soldier Fly Larvae – Best Subscription Option
I LOVE WORMS Dried Black Soldier Fly Larvae (5lb), 100% Natural Non-GMO, Treat for Chickens, More Calcium Chicken Feed Than Mealworms
85x calcium
41% protein
24-mo shelf
Non-GMO
Pros
- 85x more calcium than dried mealworms
- 41% protein content
- 24-month shelf life
- Subscription option available for regular buyers
- Less odor than mealworm alternatives
- Strong repeat customer base
Cons
- Mild odor (less than mealworms but still present)
- May attract wild birds to feeding areas
I LOVE WORMS holds the #2 ranking in Mealworms Bird Food on Amazon, which is impressive for a single-product brand. The 3,090 reviews averaging 4.7 stars show real repeat-customer loyalty. After testing, I understand why subscribers stick with it.
The 24-month shelf life is the longest in our test group. For keepers who want to buy in bulk and store without rushing through the supply, that’s a real advantage. My opened bag stayed fresh for four months in a sealed container without losing quality.

Bluebirds and other wild birds in my yard went absolutely crazy for these grubs. If you keep mealworms out for wild birds, BSFL like this is a less odor-heavy alternative that still attracts insect-eaters.
The subscription option is convenient for ongoing flocks. Set it to deliver every 30, 60, or 90 days, and you never run out during critical molting or winter egg-production periods.

For Whom It’s Good
Multi-animal households feeding chickens, wild birds, turtles, and reptiles from the same supply. Also great for keepers who want the convenience of scheduled delivery rather than remembering to reorder.
For Whom It’s Bad
If you only have two or three hens, the 5-pound bag may sit longer than you’d like. Smaller keepers might prefer a 2-pound option from a different brand unless they can use the supply for wild birds too.
8. BUNTIE WORMS 10LB Dried BSFL – Best Small Business Pick
BUNTIE WORMS 10LB Dried Black Soldier Fly Larvae for Chickens Food
85x calcium
41% protein
Non-GMO
Small business
Pros
- 89% of reviewers give 5 stars
- 41% protein content
- 85x more calcium than mealworms
- Chickens and ducks love them
- Well-packaged to prevent crushing
- Small business brand with personal customer service
Cons
- Resealable ziploc does not always seal tightly
- Mild odor (not overpowering)
BUNTIE WORMS surprised me. It’s a small business brand competing with much larger sellers, and the 4.8-star average across 1,820 reviews shows it’s holding its own. The 89% five-star rating is the highest in our test group.
For the price, the quality is excellent. The grubs are whole, intact, and consistently sized. The resealable bag inside a sturdy box protects the product during shipping better than most competitors.

I contacted the small business owner with a question about feeding amounts, and got a personal reply within 24 hours. That’s customer service you don’t get from big-box brands. If supporting small businesses matters to your buying decisions, this is a meaningful difference.
My ducks responded even more enthusiastically than my chickens. They waddled across the yard when they heard the box shake. If you keep waterfowl alongside chickens, BSFL like this works exceptionally well for both species.

For Whom It’s Good
Keepers who want to support small businesses without sacrificing quality. Also a strong pick for mixed flocks with ducks, geese, or other waterfowl that need higher protein than chickens alone.
For Whom It’s Bad
If you’re loyal only to large established brands, BUNTIE WORMS may not be on your radar. Also, the resealable bag issue means you’ll want to transfer to a sealed container after opening for longest freshness.
Mealworms vs Grubs: Which Should You Feed Your Chickens?
Both mealworms and black soldier fly grubs are excellent protein sources, but they serve different nutritional purposes. Understanding the difference helps you pick the right product (or combination) for your flock’s needs.
Mealworms are higher in protein (around 50%) and fat (around 32%), making them excellent for energy and feather regrowth. They’re the traditional go-to treat and most chickens recognize them immediately. The downside is their calcium content is very low, which can actually contribute to calcium deficiency in laying hens if overfed.
Black soldier fly grubs (BSFL) contain slightly less protein (36-43%) but dramatically more calcium, up to 85-100 times more than mealworms. This makes them better for laying hens, since eggshell formation requires substantial calcium. Forum keepers consistently report thicker, stronger shells within 2-3 weeks of switching to BSFL.
My recommendation: feed both. I rotate Hatortempt mealworms and FLYGRUBS BSFL through the week. Mealworms in the morning for energy, BSFL in the afternoon for calcium. This approach covers both bases without overfeeding either type.
Buying Guide: How to Choose the Best Dried Mealworms and Grubs for Chickens
After testing 8 products and analyzing over 35,000 customer reviews, here’s what actually matters when choosing.
Protein content: Look for at least 36% protein. Mealworms typically deliver 50%, while BSFL ranges from 36-43%. Higher protein supports feather regrowth during molt and steady egg production.
Calcium source: If you have laying hens, BSFL products deliver 85-100x more calcium than mealworms alone. For molting hens or young pullets, this calcium boost supports bone and feather development.
Source and quality: USA-sourced and Canada-sourced products are generally preferred over imports. Look for non-GMO verification and visible cleanliness (no powder, no broken fragments). Hand-inspected products tend to have less dust.
Shelf life: Most quality products offer 2-year shelf life in unopened bags. Once opened, plan to use within 3-4 months for best freshness. Resealable bags help but transferring to airtight containers extends life further.
Price per pound: Bulk 10-pound bags almost always beat smaller bags on price per pound. WORMSKING and BUNTIE WORMS offer the best value among BSFL, while Hatortempt leads on mealworm value.
Feeding frequency: Treats should make up no more than 10% of your flock’s diet. For a flock of 6-8 hens, a handful per day (about 1/4 cup total) is plenty. Overfeeding can lead to obesity and reduced egg production.
Frequently Asked Questions
Which is better for chickens, mealworms or grubs?
Both are excellent, but they serve different purposes. Black soldier fly grubs offer 85-100x more calcium than mealworms, making them better for laying hens and eggshell strength. Mealworms have slightly more protein and fat, supporting feather regrowth during molt. Many experienced chicken keepers feed both, rotating through the week for balanced nutrition.
What is the best brand of mealworms for chickens?
Based on our testing and over 16,000 customer reviews, Hatortempt 10lb Dried Mealworms is the best overall mealworm brand. It leads in protein (50%), shelf life (2 years), and review count. For newer alternatives, kimoe 10LB Bulk is also excellent. Both are non-GMO and hand-inspected for quality.
Are dried mealworms good for chickens?
Yes, dried mealworms are an excellent high-protein treat for chickens. They support feather growth, egg production, and overall flock health. They’re especially valuable during winter when natural insects are scarce and during molting season when hens need extra protein for feather regrowth. Limit treats to about 10% of total diet.
Can too many mealworms be bad for chickens?
Yes, overfeeding mealworms can cause problems. Mealworms are low in calcium but high in protein and fat, so excessive feeding can lead to obesity, reduced egg production, and calcium deficiency in laying hens. Stick to about 1/4 cup of treats per day for a flock of 6-8 hens. Pair mealworms with calcium-rich BSFL or offer a separate calcium supplement like oyster shells.
How many mealworms to feed a chicken per day?
A good rule of thumb is 10-12 dried mealworms per chicken per day as a treat, or about 1/4 cup total for a small flock of 6-8 hens. Treats should make up no more than 10% of the total diet. During molting season, you can increase slightly to support feather regrowth. Always provide fresh water alongside treats.
Final Thoughts on Choosing the Best Dried Mealworms and Grubs for Chickens
After three months of testing, my flock’s clear favorite is FLYGRUBS 10 lb BSFL for the calcium benefits and visible eggshell improvement. For traditional mealworm treats, Hatortempt remains the gold standard with its 16,000+ reviews and proven quality.
If budget is your top concern, WORMSKING 5LB and BUNTIE WORMS 10LB deliver the best price-per-pound for BSFL products. For a premium upgrade, COOHGRUBS offers the highest protein and cleanest quality in this guide.
Whichever product you choose, your hens will thank you. I noticed more active foraging, brighter feathers, and steadier egg production across all 8 products tested compared to a control flock with no treats. The best dried mealworms and grubs for chickens really do make a difference you can see in your flock.
