Week-by-week target bands from two schedules that disagree, the one Philippine figure that exists, brooder floor area by chick count, and kung kailan dapat patayin ang heater at a given room temperature.
From the table
| Week | Merck |
|---|---|
| 1 | 29.4 to 32.2 |
| 4 | 21.1 to 23.8 |
The three dates counted off your own set date, what the machine should be holding at each stage, and the one honest answer to how many chicks a clutch under an inahin actually produces: about half of it.
From the table
| Eggs set | Chicks weaned |
|---|---|
| 10 eggs | 5.1 (2.9 to 7.8) |
| 15 eggs | 7.7 (4.4 to 11.7) |
The volume a flock needs from what it eats and how hot the coop is, the temperature at which that doubles, and the second problem nobody prints: a drum in the sun holds water your birds will not drink.
From the table
| Coop, °C | Multiplier |
|---|---|
| 28.3°C | 1.58x |
| 32°C | 2.00x |
Kilos, sacks and pesos to harvest day, at the feed conversion Philippine open-sided farms work to rather than the one the breed table promises. Bring your own sack price.
From the table

| ₱1,800 | ₱68.19 to ₱80.07 |

How heavy a Boholano native bird actually is at day 21, 45, 75, 100 and 120, off the one published Philippine growth curve, and what that is worth at the PSA farmgate. No feed cost, because nobody publishes what a native chicken eats.
From the table
| Age | Mean liveweight, g |
|---|---|
| Day 75 | 430.91 |
| Day 120 | 735.96 |
What one egg costs you in feed, beside what an egg is currently fetching, and the lay rate at which those two meet. No payback period and no projected profit, because this tool exists so you can find out the answer is no.
From the table
| Lay rate | ₱1,800 |
|---|---|
| 80% | ₱5.17 |
| 90% | ₱4.60 |
Sixteen years of PSA farmgate, month by month, with the placement date counted back from the month you want to sell in. It names the two months the record actually supports and refuses to rank the other ten.

| November | 12 of 16 |
| December | 16 of 16 |
How the pages work
Four questions that come up bago dumating ang sisiw, and the answer to each of them is a table you read rather than a form you fill: hanapin mo lang ang hilera ng alaga mo. The rows either side of yours stay visible, which is what you want when you are deciding between 20 birds and 30. Three of the four also take your own numbers, under the table, if your flock is not on it.
Every number on these pages is computed at build time from a sourced coefficient, not typed in by hand. Where two sources disagree, both are shown side by side. Where nobody publishes a Philippine figure, the page says so, walang panghuhula, instead of borrowing a temperate one and hoping.
Where the figures live, and what else is here
Every price series the calculators read, with each observation dated and carrying the document it came from.
The same archive as CSV, one file per series, free to re-use with the source column intact.
Active DA and BAI quarantine areas, the case record, and what a backyard keeper is obliged to report.
The long version of what the grids compress: feeds, brooding, kulungan, disease and the money.
About these figures
Peso figures on this site are dated observations from named sources, not offers or quotes. Prices move by brand, area and week, and decisions made on them are at your own risk.
