Scratch grains — the loose mix of cracked corn, wheat, oats, and small grains that backyard flocks go after enthusiastically — are the classic poultry treat: energy-dense, forage-simulating, and nutritionally incomplete in exactly the way the scraps guide and treats guide describe. Scratch stimulates foraging behavior and provides quick energy, but it displaces balanced feed gram for gram, and its protein content falls far short of what laying and growing birds need. This page covers what scratch actually provides, the displacement economics, and the salt connection that makes free-choice scratch mixes a real risk in backyard flocks.
What Scratch Actually Provides
| Scratch Component | What It Offers | What It Lacks |
|---|---|---|
| Cracked corn | Quick energy — carbohydrates the bird burns fast | Low in lysine — the amino acid that limits performance first (the lysine guide covers why) |
| Wheat and oats | Energy with slightly more protein than corn | Still below the requirement — and NSP content the gut handles poorly without the enzyme programs commercial rations carry (the wheat guide covers the NSP story) |
| The mix as a whole | Foraging stimulation and palatability — birds work for it, which is the welfare value | Vitamins, minerals, and balanced amino acids — the premix comes only from formulated feed (the protein guide covers the displacement effect) |
The Displacement Economics
- Gram for gram, scratch displaces balanced feed. Every handful in the scratch bowl is a handful not eaten from the feeder — and at the 10% boundary, that displacement is enrichment; at 20%+, the protein and micronutrient gaps open on the schedule the vitamin guides describe.
- Evening scattering is the least-harmful pattern. Scratch given in the evening displaces the least balanced feed — birds fill up on scratch and eat their ration overnight; morning scratch displaces the day's most productive intake (the same timing logic the treats guide covers).
- The salt connection is the real backyard risk. Many commercial scratch mixes carry salt — and the salt guide covers what uncontrolled salt intake does: free-choice salt blocks plus salt-heavy scratch in a small yard is the classic backyard salt-toxicity setup, with the water system as the delivery path. Grit access compounds it: whole grains in scratch create genuine gizzard-grind demand (the grit guide covers why scratch-fed flocks legitimately need grit that pelleted-fed flocks do not).
The Honest Framing
Scratch is a treat with genuine welfare value — the foraging behavior it stimulates is real, and a backyard flock that never forages is a poorer flock. The nutritionally honest version of the habit: scatter small amounts in the evening, keep the balanced feed in the feeder as the non-negotiable base, and treat salt-heavy mixes and free-choice salt blocks as the risk they are. The treats guide covers the boundary; the egg profit guide covers what diet quality does to the per-egg economics that make the hobby worth keeping.

Backyard and small-flock operations can log feed types and egg counts on one timeline — the record that shows whether the scratch habit is costing production. The feed budget guide frames the feed-cost discipline that scales from one coop to thirty thousand birds.
