Black Soldier Fly Larvae Grubs 5 LB - High Calcium Treat for Birds

In this review the 5 lb bag of Eaton Pet and Pasture dried black soldier fly larvae is evaluated for backyard flocks and wild bird feeding. The bottom line: this product is for owners who want a nutrient-dense, USA grown treat that supports natural foraging and stronger eggshells. The review highlights how the grubs deliver high protein and an exceptionally high calcium boost compared with typical mealworms, making them especially useful during molting or for hens that need shell support.

Key Features

• USA grown and natural: The larvae are raised in the United States without added hormones, antibiotics, or pesticides for a clean treat option.
• High calcium content: With about 50x more calcium than mealworms, these grubs can help produce stronger eggshells and reduce shell defects.
• Rich nutrition profile: Packed with protein, phosphorus, fiber, lysine, and dietary fat to support feather health and energy levels.
• Sustainable sourcing: Grown on pre-consumer waste streams, the production reduces landfill waste and uses safe, AAFCO-guideline feed inputs.
• Foraging stimulation: The dried larvae encourage instinctual foraging behavior, adding enrichment and training value for chickens and ducks.

Who It's For

This product is aimed at small flock owners, homesteaders, and anyone who wants a nutrient-dense treat to support egg production and feather condition. It suits people who prioritize USA grown ingredients and sustainable feed practices, and who use treats as training rewards or enrichment.

Those who should look elsewhere include keepers who need a live feed option or require an engineered complete feed rather than a supplemental treat; this is a treat and supplement, not a full feed replacement.

Pros & Cons

Pros

• High calcium and protein content supports stronger eggshells and better feather regrowth.
• Made in the USA from natural, antibiotic- and hormone-free production methods.
• Sustainably produced on pre-consumer waste, offering an environmentally conscious option.
• Effective as a training treat and encourages natural foraging behavior.

Cons

• As a dried treat, it is a supplement rather than a complete feed; owners must still provide balanced feed.
• Some users may find 5 lb bags large if they only keep a very small flock and prefer smaller quantities.
