Best Lysine-Rich Foods for Chickens

Ranked by lysine content among foods safe for chickens in the Creature Feast catalog.

Lentils per 100g cooked: 630mg lysine Lentils are the richest lysine source among chicken-safe plant foods. Lysine is the second most limiting amino acid in poultry diets after methionine and is critical for muscle growth, feather development, and immune antibody production in laying hens.

Peas per 100g: 317mg lysine Peas are an excellent lysine source that complements the methionine in grains and seeds. The lysine in peas supports the immune system's antibody production, helping chickens resist the respiratory diseases that commonly circulate in backyard flocks.

Oats per 100g dry: 523mg lysine Oats provide moderate lysine for a cereal grain, higher than corn or wheat. When fed alongside legume treats like peas or lentils, oats help create a more complete amino acid profile that better supports the chicken's protein needs for egg and feather production.
