Creating a Balanced Diet for Backyard Chickens

A hen’s body is a remarkable system. Every day she converts what she eats into energy, feathers, bone, muscle, and — if she’s a laying hen — a complete egg with its own complex structure of shell, membrane, white, and yolk. That’s an extraordinary amount of biological work, and it all depends on what you put in the feed dish.

Most backyard keepers start with a bag of commercial layer feed and assume they’re covered. And for basic survival, they probably are. But a truly balanced diet goes beyond the minimum. It’s the difference between a hen that lays and a hen that thrives — bright-eyed, glossy-feathered, actively foraging and genuinely healthy.

The Foundation: A Quality Feed

Start with a feed that uses whole, identifiable ingredients. You should be able to see grains, seeds, and herbs in the mix — not a uniform pellet or crumble that could contain anything. A good base feed provides roughly 16–18% protein for laying hens, with calcium levels around 3–4% to support strong eggshells.

But percentages only tell part of the story. The source of that protein matters enormously. Plant-based proteins from a variety of seeds and legumes provide a broader amino acid profile than any single ingredient. And the vitamins and minerals should come from real food sources whenever possible — not just synthetic additives sprayed onto a carrier.

Supplementing Wisely

Oyster shell should be available free-choice at all times for laying hens. Unlike the calcium baked into feed, oyster shell dissolves slowly in the gizzard, providing a steady release of calcium right when the hen needs it most — overnight, when the eggshell is being formed. Keep it in a separate dish so hens can self-regulate.

Grit is essential if your hens don’t have access to natural gravel and stones. Chickens don’t have teeth; they grind their food in the gizzard using small stones. Without grit, they can’t properly break down whole grains and seeds, which means they’re not extracting the full nutritional value from their feed.

Kitchen scraps and garden extras can be a wonderful supplement, but they should be treats, not the main course. Leafy greens, herbs, berries, squash, and cooked grains are all excellent. Avoid anything moldy, anything heavily salted or processed, and the nightshade family in large quantities — raw potatoes and tomato leaves can cause problems.

Seasonal Adjustments

A balanced diet isn’t static. In winter, hens need more calories to maintain body temperature, so increasing the grain ratio — especially corn — makes sense. During molt, they need extra protein to regrow feathers, so supplementing with black soldier fly larvae or sunflower seeds helps them through that demanding process.

In summer, when hens are foraging more and eating bugs, grass, and whatever they find in the yard, their dietary needs shift again. They’re getting more variety on their own, so the feed serves more as a nutritional safety net than a sole source.

Watch and Learn

The best indicator of a balanced diet is the flock itself. Bright combs, clean vents, strong eggshells, rich yolk color, and active foraging behavior all tell you things are working. Dull feathers, thin shells, reduced laying, or lethargy are signals that something in the diet needs attention.

I formulate Happy Chicks Feed with this whole picture in mind — not just the protein number or the calcium percentage, but the full range of what a hen’s body needs to do its extraordinary daily work. Every ingredient is chosen for a reason, measured by hand, and mixed in small batches. Because a balanced diet isn’t about hitting numbers on a label. It’s about feeding a living system with the care it deserves.
