Best Vitamin B1 (Thiamine)-Rich Foods for Chickens

Ranked by vitamin b1 (thiamine) content among foods safe for chickens in the Creature Feast catalog.

Sunflower Seeds per 100g: 1.48mg thiamine (Vitamin B1) Sunflower seeds are a strong thiamine source for chickens. Thiamine supports carbohydrate metabolism and nervous system function, and deficiency in poultry causes the distinctive star-gazing posture (opisthotonus) where the bird's head bends backward involuntarily.

Lentils per 100g cooked: 0.17mg thiamine Lentils provide good thiamine that supports the energy metabolism chickens rely on for the demanding processes of daily egg production and thermoregulation. Cooking does reduce thiamine somewhat, but cooked lentils still deliver a meaningful contribution.

Oats per 100g dry: 0.76mg thiamine Oats deliver solid thiamine alongside their fiber and protein. The B1 in oats supports the carbohydrate-to-energy conversion that fuels a chicken's constant foraging activity, body temperature maintenance, and reproductive output.

Peas per 100g: 0.27mg thiamine Peas contribute moderate thiamine in a readily digestible form. As part of a varied treat rotation, peas help ensure the flock's B-vitamin intake stays adequate to support the nervous system and energy metabolism.
