Scratch for chickens is a treat-only mix of grains and seeds—commonly cracked corn, wheat, and oats—that supplements a complete layer feed, not a replacement for it. It provides enrichment and energy but lacks balanced nutrition.
A new chicken keeper sees a bag labeled “scratch” at the feed store and wonders whether it replaces the layer pellets. The short answer is no—but the real question is what scratch actually does, and how to use it without accidentally shortchanging your flock’s health. Scratch is the chicken equivalent of candy: fine in small doses, a problem as a main course.
What Scratch Is Made Of
Scratch grains are a loose mixture of cracked or whole cereal grains and seeds. Common ingredients include cracked corn, wheat, oats, barley, millet, milo (sorghum), and sunflower seeds. The exact blend varies by brand and region—there is no universal formula. Some mixes lean heavily on cracked corn for energy, while others add more protein seeds like sunflower. What every scratch has in common: it is high in carbohydrates and/or fat, and low in vitamins, minerals, and protein compared with complete layer feed.
Scratch vs. Complete Feed: The Key Difference
Complete layer feed or starter/grower feed is formulated to deliver every nutrient a chicken needs in the right ratio—protein for egg production, calcium for shells, vitamins for immunity. Scratch delivers calories and little else. Relying on scratch as a primary food creates nutritional gaps that hurt egg quality, feather condition, and overall flock health. The consistent guidance from poultry sources: scratch should never make up more than roughly 10 percent of a chicken’s daily diet.
A healthy routine looks like this: keep a complete layer feed available at all times. Offer scratch only as a treat, typically in the afternoon after birds have already eaten their fill of balanced feed. Scatter it on the ground or in bedding so chickens scratch and forage for it—the activity itself is part of the enrichment. Provide grit alongside scratch to help digestion, since whole or cracked grains are harder to break down than pelleted feed.
How Much and When to Feed Scratch
The safest serving rule is simple: scatter only as much scratch as the flock can finish in about 10 to 15 minutes. Overfeeding is the most common mistake. When chickens fill up on scratch, they eat less of their complete feed, which leads to nutritional imbalance over weeks and months. A few handfuls per bird in the afternoon works for most small flocks. Scratch is also a useful training tool—chickens quickly learn to come when they hear the grain bucket.
Winter is the one season when a slightly larger scratch portion makes practical sense: the extra carbohydrate calories help birds maintain body heat. Even then, the 10-percent rule still applies. Chicks should not get scratch at all. Their digestive systems are not ready for whole or cracked grains, and they need the concentrated nutrition of starter feed to develop properly.
Common Mistakes to Avoid
Three errors show up repeatedly among new keepers. Feeding scratch as the main ration is the worst—it shortchanges the birds on protein and calcium. Giving scratch to chicks is second; wait until they are fully grown adults. Treating all scratch blends as interchangeable is third: a bag heavy on cracked corn and light on variety offers less nutritional diversity than one with oats, barley, and seeds. Check the ingredient list if you care about what your flock gets, or compare top-rated scratch blends for laying hens to see what experienced keepers recommend.
For a DIY scratch mix, equal parts of cracked corn, whole oats, wheat, barley, split peas, and sunflower seeds produces a reasonable homemade blend. Even then, remember it is a supplement—the layer feed is still the star of the diet.
