Best Vitamin B12 (Cobalamin)-Rich Foods for Chickens

Ranked by vitamin b12 (cobalamin) content among foods safe for chickens in the Creature Feast catalog.

Lentils per 100g cooked: trace amounts (chickens rely on insects and microbial synthesis) Lentils contain trace amounts of B12, though plant foods are generally poor sources. Chickens primarily obtain B12 from insects, worms, and microbial synthesis in the cecum. For free-ranging flocks, B12 deficiency is rare because even modest insect intake provides adequate levels.

Oats per 100g dry: negligible B12 (supports cecal bacteria that produce B12) Oats do not contain significant B12, but their fiber supports the cecal fermentation where gut bacteria produce some B12 that the chicken can absorb. A healthy gut microbiome fed by fiber-rich foods like oats indirectly supports B12 status in the flock.
