How Shira Calculates Your Poultry KPIs Automatically
A walkthrough of how Shira turns your daily egg counts and feed records into HDP, FCR, mortality rate, and break-even analysis — automatically, with no spreadsheets needed.
How Shira Calculates Your Poultry KPIs Automatically
You know you should track HDP, FCR, and mortality rate. You know these numbers drive your profitability. But calculating them by hand — dividing, multiplying, comparing weeks, adjusting for dead birds — takes time you do not have.
Here is how Shira does it for you from the data you already enter.
What you enter (the inputs)
Every day, you record three things:
1. Eggs collected. Total count, once per day, after your final collection. Takes 10 seconds.
2. Mortalities. If any birds died today, record the count. Most days this is zero. Takes 5 seconds.
3. Feed consumed. Kilograms of feed put in the feeders today. If you fill feeders twice, enter the total. Takes 10 seconds.
That is it. Three numbers. Under 30 seconds per day.
What Shira calculates (the outputs)
From those three inputs, the app produces seven KPIs in real time:
Hen Day Production (HDP)
Formula: (Eggs collected ÷ Live hens today) × 100
The app maintains a running live bird count. It starts with your initial placement number and subtracts each mortality you record. You never have to calculate the denominator yourself.
What you see: Today's HDP, 7-day average, 30-day trend graph, comparison to the breed standard curve for your flock's age.
Alert: If the 7-day average drops more than 5 percentage points below the expected curve for your flock's age, you get a notification. This catches problems before they become crises.
Feed Conversion Ratio (FCR)
Formula: Total feed consumed (kg) ÷ Total egg weight (kg)
The app estimates total egg weight from your egg count multiplied by the average egg weight for your breed and flock age (which it knows from the breed profile). If you record actual egg weight (optional — using a scale on a sample), it uses your number instead of the estimate.
What you see: Weekly FCR, monthly FCR, trend over time. A rising FCR line means efficiency is declining.
Alert: If FCR rises above your set threshold (or the breed standard + 0.3), you get a notification suggesting common causes: feed waste, feed quality, water restriction, disease.
Mortality Rate
Formula: (Total deaths to date ÷ Initial bird count) × 100
What you see: Cumulative mortality percentage, daily mortality, weekly mortality. A graph showing when deaths occurred — clusters indicate disease events.
Alert: If daily mortality exceeds 0.1% (3 birds per 1,000) for two consecutive days, you get a notification. Early response to mortality spikes saves flocks.
Feed Cost Per Egg
Formula: Daily feed cost ÷ Eggs collected
This tells you the direct feed cost of each egg. You set your feed price per kilogram once (and update it when the price changes). The app calculates daily.
What you see: Cost per egg today, weekly average, monthly trend. When egg selling price is entered, the app shows margin per egg.
Break-Even HDP
Formula: (Total daily cost per hen ÷ Price per egg) × 100
You set your full cost per hen per day (feed + labour + overhead, amortised). The app calculates the minimum HDP needed to break even.
What you see: A horizontal line on your HDP graph showing the break-even threshold. When actual HDP crosses below this line, the graph turns red.
Revenue Per Hen Per Day
Formula: (Eggs per hen per day × Price per egg)
A simple but powerful number that tells you what each hen is earning.
What you see: Daily and weekly revenue per hen. Compare across flocks if you have multiple houses.
Days to Replacement
Formula: Based on HDP trend regression
The app looks at the last 14-30 days of HDP data, calculates the rate of decline, and projects when HDP will cross below your break-even line.
What you see: "At current rate, HDP will reach break-even in approximately 47 days." This gives you lead time to order replacement birds.
The dashboard view
When you open the poultry dashboard, you see:
Top row: Today's HDP, today's FCR, cumulative mortality, and feed cost per egg — the four most critical numbers at a glance.
Main chart: HDP over time — a line graph showing daily HDP (faded dots) and the 7-day average (bold line). The breed standard curve overlaid in grey so you can see how your flock compares to expected performance. Break-even line in red.
Below the chart: FCR trend, mortality events (marked as dots on a timeline), and revenue summary.
Alerts panel: Any active alerts — production drop, mortality spike, FCR increase, upcoming vaccination, or approaching replacement date.
Multi-flock comparison
If you have multiple houses or batches, each has its own set of KPIs. The app also shows:
- Side-by-side comparison of HDP across flocks
- Which flock has the best FCR and which has the worst
- Combined farm-level production and revenue
This is essential for multi-house operations where one house might be underperforming without you realising it — because the combined egg count still looks reasonable.
Monthly report
At the end of each month, the app generates a summary:
- Average HDP for the month
- Total eggs produced
- Total feed consumed
- FCR for the month
- Total mortalities
- Revenue and feed cost
- Profit margin
You can review this in the app or export it. This becomes your monthly farm report — the same kind of report that commercial operations produce, generated automatically from data you already entered.
From data to decisions
The KPIs are not numbers for their own sake. Each one points to specific decisions:
- HDP dropping below curve → Investigate (water, feed, disease, lighting)
- FCR rising → Check feed quality, reduce waste, cull non-producers
- Mortality spike → Call vet, implement emergency biosecurity
- Feed cost per egg approaching selling price → Margins are thin — address costs or raise prices
- Days to replacement < 60 → Order new birds now
The app gives you the numbers. You make the decisions. But the decisions are based on facts, not feelings.
