Nature’s Protein for Strong, Happy Chickens!

Your flock deserves the best, and Mother Nature has it figured out—Black Soldier Fly Larvae for chickens are a calcium superfood!

That’s why we created GrubFuel, a premium blend of 100% all-natural Black Soldier Fly Larvae  (BSFL) that packs a powerful punch of calcium, protein, healthy fats, and essential nutrients.

It’s the ultimate foraging treat to keep your hens thriving, feathers shining, and egg production strong!


Why Chickens (and Their Humans) Love GrubFuel Black Soldier Fly Larvae for chickens

✔️ Protein-Packed & Nutrient-Dense – With naturally high levels of protein and fat, GrubFuel helps support strong muscles, vibrant feathers, and top-notch egg-laying.

✔️ Supports Natural Foraging Instincts – Scatter GrubFuel in the run and watch your flock scratch, peck, and feast just like they would in the wild.

✔️ Better Than Mealworms – BSFL contain more calcium (great for strong eggshells!) and a better nutrient profile than traditional dried mealworms.

✔️ Sustainably Raised in the USA – Our Black Soldier Fly Larvae for chickens are free of hormones, antibiotics, and pesticides—just pure, wholesome insect protein straight from nature.

✔️ Eco-Friendly & Sustainable – Unlike traditional protein sources, Black Soldier Fly Larvae farming requires fewer resources and leaves a tiny environmental footprint. That means you’re not just feeding your flock—you’re making a better choice for the planet! 


How to Use GrubFuel

GrubFuel is not a complete feed (chickens still need a balanced diet), but it makes the perfect high-protein supplement or training treat! For more nutrient support, grab a bag of Buff Clucks Herb Supplement.

🥚 For laying hens – Sprinkle a handful of Black Soldier Fly Larvae into their feed or scatter on the ground for natural foraging.
🐣 For chicks (over 2 weeks old) – Crush into smaller pieces and mix with starter feed for a protein boost.
🐔 For all backyard chickens – Use Black Soldier Fly Larvae as a treat, training reward, or occasional protein boost to keep your flock thriving.

Shelf Life: Store in a cool, dry place. Reseal after opening to maintain freshness.

Your chickens will love the taste. You’ll love the nutritional benefits. And the planet will thank you for choosing a sustainable, all-natural Black Soldier Fly Larvae for chickens. 🐓💚
