Poultry farm profit margin is the gap between what a flock earned at settlement and what it cost to raise — and most growers discover the number too late to change it. The margin is not the settlement check; it is the settlement check minus every cost attributable to that flock: feed, chicks, bedding, energy, labor, repairs, medication, and the fixed costs the flock absorbed its share of. This page covers the margin calculation, the levers that move it most, and the records that make margin visible during the flock instead of after it.
What Margin Actually Includes
| Component | Example Flock | Where the Record Lives |
|---|---|---|
| Settlement income (revenue) | Contract payment on 186,240 lb delivered | Settlement sheet — recorded against the flock, checked by the comparison method |
| Feed (largest cost) | ~$160,350 — over 85% of total cost in the example | Delivery tickets logged by weight, phase, and date |
| Chicks | ~$6,000 at $0.20 each | Placement records |
| Bedding, energy, labor, repairs, meds | ~$11,700 combined in the example | Per-flock expense entries with dates and categories |
| Total cost | ~$178,050 | Sum of the above — the break-even denominator |
The Margin Levers, Ranked by Impact
- Feed price (largest lever). Feed is over 85% of flock cost in the example. A $0.05/lb delivered-price change moves total cost by about $8,000 across the cycle — nearly $0.045/lb of break-even. Negotiating price or timing purchases beats almost any management change; see the feed cost guide for the leak side.
- Feed conversion (largest controllable lever). Every 0.01 of FCR improvement on the example flock saves roughly 1,900 lb of feed — about $960 per flock. The FCR guide covers the benchmarks by age; the feed chart shows the intake curve it is measured against.
- Mortality (pounds you already paid for). Each 1% of mortality on 30,000 birds is 300 birds — feed consumed without saleable weight. The cause-signature table covers the patterns that precede it.
- Average weight at catch. A flock catching 0.4 lb light on 29,100 saleable birds delivers roughly 11,600 lb less — the margin impact dwarfs almost every other line. The growth bands guide shows when to act on weight deviation.
Margin During the Flock, Not After
The reason margin usually surfaces at settlement instead of during the grow-out: costs are recorded monthly and income arrives once. Per-flock expense attribution changes that — when every feed delivery, energy bill, and repair is tagged to the flock as it happens, cost per bird and projected margin are visible weekly, while the causes are still correctable. A feed-price surprise caught in week 3 is a purchasing decision; the same surprise found at settlement is a fait accompli.
Tracking Margin in Poultry Log™
Poultry Log™ computes margin from the same records this page describes: settlement income recorded against the flock, expenses tagged to it, and the cost-per-bird and cost-per-pound outputs that make flocks comparable across seasons. The profitability dashboard carries the multi-flock trend; the break-even price supplies the floor; and the budget template projects the next placement's margin from your own history instead of hope.
