Golden Dried Black Soldier Fly Larvae - Boost Egg Production Naturally

In this review the reviewer tested GrubTerra Golden dried black soldier fly larvae as a high-protein, calcium-rich supplement for backyard flocks and wild birds. The bottom line: this product is for poultry keepers who want a compact, non-GMO treat that can support egg production and feather health without refrigeration. The single biggest reason to buy is its nutrient density - notably high protein and calcium - delivered in a resealable pouch that makes feeding and storage straightforward.

Key Features

• Premium sourcing: Larvae are sourced from USA, Mexico, Canada and Costa Rica, which supports traceability and consistent quality for flock feeding.
• Nutrient-dense supplement: The dried larvae deliver 36-42 percent protein and 30-40 percent healthy fat to support growth and energy.
• Calcium boost for layers: With roughly 75 times more calcium than many other bird feed treats, these larvae can help support egg production in laying hens.
• No additives or preservatives: Naturally dried and served without additives, the product aims to preserve the whole nutrient profile for better poultry health.
• Resealable pouch: A zip-top pouch keeps treats fresh for up to one year when stored in a cool, dry place and eliminates the need for refrigeration.
• Easy to feed: Dried form can be sprinkled by hand, put in a dish, or mixed with feed to save time versus live worms.

Who It's For

This product is best for backyard chicken keepers, small hobby farms and bird enthusiasts who want a concentrated protein and calcium supplement to support laying hens, ducks, turkeys and pet birds. The convenient dried form suits people who prefer to reduce handling time compared with live feeders and who value non-GMO, traceable sourcing.

It is less suitable for those seeking a complete feed or for flocks with birds that consistently refuse insect treats; some customers report mixed acceptance by individual birds. Also, people who need a bag smaller than 5 lb or who require refrigerated live feed should look elsewhere.
