Black Soldier Fly Larvae for Chickens: The Best Treat for Backyard Flocks

Why Backyard Chicken Keepers Love Black Soldier Fly Larvae
If you keep backyard chickens, you have probably already discovered that your flock goes absolutely wild for live grubs. Black soldier fly larvae (BSFL) are the premium version of that instinct — packed with more protein and calcium than any other common treat, and they encourage natural foraging behavior that keeps your birds mentally and physically healthy.
BSFL Nutrition for Chickens
| Nutrient | BSFL | Mealworms | Why It Matters |
|---|---|---|---|
| Protein | ~17% | ~20% | Supports feather growth and egg production |
| Calcium | 9,340 mg/kg | 30 mg/kg | Strong egg shells, bone health |
| Fat | ~14% | ~13% | Energy for laying hens |
| Ca:P Ratio | 6.92:1 | 0.04:1 | BSFL provide 300x better calcium balance |
The calcium difference is staggering: BSFL contain 311 times more calcium than mealworms. For laying hens that need calcium for strong egg shells, this is not a minor upgrade — it is a fundamental improvement in nutrition.
Benefits for Backyard Chickens
Strong Egg Shells
Thin or soft-shelled eggs are a calcium deficiency symptom. BSFL deliver the most concentrated natural calcium source available for poultry, supporting thick, strong shells without relying solely on oyster shell supplements.
High Protein for Feather Growth
Chickens need extra protein during molting season when they shed and regrow feathers. At 17% protein, BSFL provide a protein boost that supports faster, healthier feather regrowth.
Natural Foraging Enrichment
BSFL wriggle actively when scattered on the ground, triggering natural scratching, pecking, and foraging behavior. Bored chickens develop destructive habits like feather picking — live BSFL provide mental stimulation that keeps flocks engaged and content.
Sustainable Protein
Black soldier fly larvae are one of the most environmentally sustainable protein sources available. They convert organic waste into high-quality animal nutrition with a fraction of the land, water, and energy that traditional feed crops require.
How to Feed BSFL to Chickens
- Small flock (3-6 hens): 1/4 cup per day as a treat
- Medium flock (6-12 hens): 1/2 cup per day
- Large flock (12+): 1 cup or more per day
Important: BSFL should be a supplement — not a feed replacement. Keep them to 10-15% of total daily intake. The remainder should come from a balanced layer feed.
Scatter on the ground for foraging enrichment, or place in a dish. Chickens eat them enthusiastically either way — expect a feeding frenzy.
Storage
Store in the refrigerator at 50-55°F for 2-3 weeks. No feeding or maintenance needed. Chickens eat BSFL cold or at room temperature — they do not care.
BSFL vs Mealworms for Chickens
Mealworms are the traditional chicken treat, but BSFL are nutritionally superior in every calcium metric. If your hens are laying soft-shelled eggs or you want to reduce your dependence on oyster shell supplements, BSFL are the upgrade.
Also Great for Reptiles
BSFL are not just for chickens. They are a premium calcium supplement for bearded dragons, leopard geckos, chameleons, and other reptiles. The same calcium that builds strong egg shells builds strong reptile bones. See our full BSFL collection.
