Grubblies Black Soldier Fly Larvae Chicken Treats - Strong Eggshells

Our review of Grubblies Hometown Harvest is written for backyard poultry keepers looking for a natural, high-calcium treat that encourages foraging and supports laying hens. The bottom line: these oven-dried black soldier fly grubs are a nutrient-dense snack produced in the US and Canada that genuinely helps with calcium and amino acid intake, which can translate to stronger eggshells and healthier feathers when used as part of a balanced diet.

Key Features

• Oven-dried black soldier fly grubs: The drying process yields a shelf-stable treat that is easy to store and handle while preserving protein and mineral content.
• Sustainably grown: Grubblies are sourced from farms in the US and Canada and raised on fruits, vegetables, and grains, reducing concerns about questionable feed inputs.
• High calcium content: These grubs contain far more calcium than mealworms, helping support strong eggshells and bone health for layers.
• Rich in essential amino acids: Packed with lysine and other amino acids that support immunity, skin health, and feather quality.
• Promotes natural foraging: Scatter by hand or on the ground to encourage natural scratching and foraging behaviors in chickens and other birds.

Who It's For

This product is best for backyard chicken owners, small homesteaders, and keepers of other poultry or insect-eating pets like ducks, turkeys, turtles, and some lizards who want a high-protein, natural treat option. It suits people who prioritize sustainably sourced ingredients and those looking to boost calcium and amino acids in a laying flock.

Those seeking a primary feed or a low-cost bulk protein replacement should look elsewhere; Grubblies are intended as a treat or supplement rather than the main diet. Owners sensitive to strong insect smells or with birds on very strict medical diets should consult a vet before introducing new treats.
