Pyridoxine (Vitamin B6) is central to amino acid metabolism — it helps the body process and rearrange amino acids from dietary protein into the specific proteins the hen needs for egg production, immune function, and tissue maintenance. Given that a laying hen builds an entire egg's worth of protein every 25 hours, the demand for efficient amino acid metabolism is enormous. B6 also supports the production of hemoglobin for red blood cells, neurotransmitters for the nervous system, and antibodies for immune defense.
For backyard flocks, B6 is relevant during periods of high protein turnover: peak laying, molting, recovery from illness, and growth in young birds. Because B6 is involved in processing protein, hens on higher-protein diets (such as during molt when extra protein is supplemented) actually need proportionally more B6 as well.
Like other water-soluble vitamins, B6 cannot be stored in large amounts and needs consistent daily replenishment. It is present in a wide range of foods, making outright deficiency uncommon in well-managed flocks, but marginal status can reduce overall productivity without producing obvious clinical signs.
Laying hens need about 3 to 4 mg of Vitamin B6 per kilogram of feed. Commercial feeds include this. Good natural sources include sunflower seeds, bananas, sweet potatoes, and brewer's yeast. When supplementing extra protein during molt, the B vitamin supply should increase in parallel — brewer's yeast covers both B6 and other B vitamins nicely.
0.0% of daily nutrient intake
Vitamin B6 (Pyridoxine) makes up 0.0% of your chicken's total daily nutritional requirements by weight. That's a tiny amount — but it matters.
Reduced egg production, poor appetite, slow growth, jerky movements and incoordination, anemia, reduced immunity, poor feather quality, decreased hatchability in fertile eggs
B6 is water-soluble and excess is excreted readily. Dietary toxicity in poultry is not a documented concern. Extremely high supplemental doses over long periods could theoretically cause nerve damage, but this is not relevant to normal feeding.
