The Role of Grains and Seeds in Chicken Diets

My father could walk through a field and tell you what the soil was doing just by looking at what was growing. He understood something most of us have forgotten: that the plants and grains that grow in a place are inseparable from the health of the animals that eat them. When I formulate feed, I think about that connection constantly.

Grains and seeds are the foundation of any good chicken feed. They provide the carbohydrates that fuel a hen’s daily activity — the scratching, the foraging, the remarkable biological work of producing an egg almost every day. But not all grains are created equal, and the differences matter more than most feed labels let on.

The Grains That Matter

Whole oats are one of the most underrated ingredients in poultry nutrition. They’re high in fiber, which supports healthy digestion, and they contain beta-glucans that naturally boost immune function. Most commercial feeds skip oats because they’re bulkier and more expensive than corn. That tells you something about priorities.

Wheat provides a different kind of energy — more protein than corn, with a better amino acid profile for egg production. Heritage wheat varieties, the kind my father would have recognized, tend to be more nutrient-dense than the modern dwarf varieties bred purely for yield. When I can source heritage grains, I do.

Corn has its place. It’s an excellent energy source, especially heading into winter when hens need extra calories to maintain body heat. But corn shouldn’t be the majority of any feed — it’s too low in protein and too high in starch to carry the load alone. Think of it as the supporting cast, not the lead.

Seeds: Small but Mighty

Flaxseed is the ingredient I get the most questions about. It’s rich in omega-3 fatty acids, which don’t just benefit the hen — they pass directly into the egg. Hens fed flaxseed produce eggs with measurably higher omega-3 content. That’s not marketing; it’s biochemistry.

Sunflower seeds, especially black oil sunflower seeds, are packed with vitamin E and healthy fats that support feather quality and skin health. During molting season, I increase the sunflower seed ratio because hens need those extra fats and proteins to regrow their plumage.

Millet and sesame round out the mix. Millet is easily digestible and a good source of B vitamins. Sesame provides calcium and zinc in forms that hens absorb more readily than synthetic supplements. Together, these seeds create a nutritional profile that no single grain can match on its own.

Why Quality Sourcing Matters

I source organic grains whenever possible, not because it makes for a better label, but because organic grains haven’t been desiccated with glyphosate before harvest. That’s a common practice in conventional grain farming — spraying the crop with herbicide right before harvest to dry it down for easier combining. Those residues end up in the feed, and from the feed into the egg.

Every ingredient in Happy Chicks Feed is something I can trace back to its source. I measure by hand, I mix in small batches, and I use the knowledge my father gave me about what plants can do. Your hens deserve grains and seeds that were grown with the same care you bring to keeping them.
