Best Protein-Rich Foods for Chickens

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

Lentils per 100g cooked: 9g protein Lentils are one of the richest plant-based protein sources available to backyard chickens, delivering a concentrated amino acid profile that supports egg production and feather growth. Cooked lentils are soft enough for hens to eat readily and are especially valuable during molt when protein demands spike to 20-22%.

Sunflower Seeds per 100g: 21g protein (rich in methionine) Sunflower seeds pack substantial protein alongside healthy fats, making them a dual-purpose supplement for laying hens. The methionine content is particularly valuable since methionine is the first limiting amino acid in poultry diets and is critical for feather keratin synthesis during molt.

Peas per 100g: 5g protein (high lysine content) Peas provide a well-balanced plant protein that chickens eat eagerly, whether fresh, thawed from frozen, or lightly cooked. The lysine content in peas complements the methionine in grains, creating a more complete amino acid profile when fed alongside scratch grains.

Oats per 100g dry: 13g protein Oats offer moderate protein with excellent digestibility for chickens. Rolled or steel-cut oats soaked briefly in warm water make a protein-rich warm mash that is especially appreciated on cold winter mornings when hens need both protein and energy to maintain body condition and egg production.

Barley per 100g dry: 12g protein Barley provides moderate protein and is one of the better grain-based protein sources for supplementing a chicken's diet. Hulled barley has slightly higher protein than pearled barley and can be sprouted to increase digestibility and nutrient availability for the flock.
