41 articles on data gaps for Philippine backyard keepers, every peso figure sourced and dated.
The figures no Philippine institution publishes, named one at a time and dated. A gap stated plainly is more useful than a plausible number with nothing behind it, and this is the register of every one this site has run into.
Two Philippine standards written by the same bureau authorise the two words on an egg tray on opposite terms: one asks a farm to comply and then label its own eggs, the other asks for a certificate from a competent authority its own scope puts in the future tense. One caps outdoor range at a square metre a hen and forbids beak trimming; the other excludes any outdoor area from its space count and heads beak trimming Optional.
DA Administrative Order No. 5 s. 2019 gives the spent hen her own row in the transport rules, and of the twenty species rows in that section hers is the only one that closes a geographic route: no culls from Luzon to Visayas or Mindanao, and no spent chickens between major islands at all. What none of the four Philippine documents that legislate on her will tell you is which bird in your kulungan she is. Two fingers between the pubic bones answers that, and the sheet it comes from was written in Mississippi.
One Philippine institution ran the textbook breeding setup on two stock groups for eight months and got 41 to 48 percent of the eggs it set to hatch. The reference figure every guide quotes is 70 to 77. Plan on the measured one.
Chicken liver retails above the fully dressed broiler it came out of, ₱226.52 against ₱213.24 a kilo in July 2026. A dressing percentage tells you what the bird lost. It says nothing about what the losses are worth.
Twenty tropical cyclones enter the Philippine Area of Responsibility in an average year and eight or nine of them cross the country, and the enforceable Philippine standard for broiler housing names two structural loads, neither of which is wind. The number that does exist sits in the structural code, one basic wind speed per province, and at four of the ten PAGASA stations checked here the strongest wind already on record is above the speed that province is designed against. What is left for a bakuran is not a stronger building. It is a signal, a lead time, and a decision about where the birds go.
Every predator guide a Filipino keeper finds first was written against animals that do not live here. This one works from the aperture a Philippine threat actually passes, the one peer-reviewed record of a named Philippine animal taking chicks, and the peso line in the Local Government Code that decides where a stolen manok gets reported.
The litter moisture every broiler manual sets as a ceiling, under 35%, is the top of the 25 to 35% band an oocyst needs to sporulate. Dry litter and litter too dry to sporulate are not the same target, and no page in this SERP says so.
₱77.90 per kilo liveweight is the number everyone quotes for a Philippine broiler. It comes from one 2017 table in Pampanga, and the paper carrying it prints the same figure twice in two different units.
Every ventilation rule on the first screen of results is an area rule written for a sealed box in a cold winter. The Philippine standards give no area at all. They give positions, and both positions depend on a wind direction that flips between amihan and habagat. Held against PAGASA wind normals at four stations, the rate a Philippine order asks for is satisfied by air crossing the mesh at 3.5 centimetres a second, while the speed a hot bird needs is above the mean wind at every station checked.
Almost every page answering this question starts at the Department of Agriculture, which is the one layer that does not reach a backyard flock at all. The paperwork that does reach it is local, it is cheap, and it runs on statutory clocks nobody quotes.
Every guide tells you to keep water available and then stops, because the honest answer to how much is a ratio rather than a figure and nobody wants to write that. Four published sources give four different water-to-feed ratios, one DA regional office quietly published a per-hen intake table in gallons, and the Philippine welfare code requires an annual water test against an appendix that is not in the document. This page holds all of it in one place, with the drinker counts and the eight-hour limit that go with it.
The distance from the layer house to the palengke has gone from ₱0.69 the wrong way in 2018 to ₱1.94 in the first half of 2026. The two series it is drawn from are not the same egg, and the year the subtraction came out negative is the proof.
Eight small layer farms in Leyte were all deworming every three to six months and 92.2% of their faecal samples still came back positive. That is the whole case against a calendar, and it is the only Philippine measurement there is.
The American list starts with avocado, and Merck says chickens are relatively resistant to it. The Philippine list starts with amag, because a survey of rice bran here found aflatoxin at 123 times the level Merck says young poultry tolerate, and because the national standard for contaminants in feed says out loud that it is protecting the person eating the chicken.
The layer pillar on this site says the pullet premium is a figure you cannot look up, set against ₱270 from 2018 and a rearing cost you have not run yet. This is that rearing cost, run: feed from the Hy-Line rearing table, brooder electricity at the August 2026 Meralco rate, and mortality taken off the top, turned into the pullet quote at which buying and rearing cost the same.
Batanes swings 148 minutes of daylight across the year and Tawi-Tawi swings 35, against 361 in Iowa. So the shortening-autumn story behind every molting page a Filipino keeper finds does not describe this country. What Berry (2003) says actually starts a molt in the ancestor of the laying hen is broodiness, and what stops one on a Philippine standard is nothing at all, because no Philippine standard mentions moulting.
Every page on the first screen of results treats heat stress as a summer emergency, which is what it is in Ohio. Measured against the Merck comfort band, all 36 station-months at three PAGASA stations are above the heat-stress threshold on the monthly mean and 24 of them are above it even at the coolest hour before dawn. So the question here is never whether the birds are heat stressed. It is which of four levers is still worth pulling, and the humid air rules out the one every foreign guide recommends first.
Every page about bird flu in this country answers where it has been. The nine-year outbreak record also answers when, and the reported dates bunch hard into February, March and April.
Sacks bought over kilos sold is the only feed conversion a backyard keeper can measure. Every published figure, Philippine or imported, is computed a different way, and holding one against the other is the mistake almost every guide makes.
Aviagen says 2,360 grams at day 35. The only Philippine figure to hold it against is a table of what commercial growers were aiming at, a third of whom miss their own targets, and not one of them was a bakuran flock.
Nobody publishes a backyard broiler mortality rate for the Philippines. What is published is enough to price a death by the day it lands, and a chick lost in week one is not the same loss as a bird lost on day 35.
The grower fee is unpublished in the Philippines, so this is not a peso-against-peso comparison. It is what each arrangement costs you in risk, what the archive can actually price on the independent side, and the ten things to extract from the contract in front of you.
Nobody publishes eggs per hen per month, so every page that quotes one has divided an annual total by twelve. Here is the whole laying year in 28-day months, differenced out of the breeder standard, priced against the June 2026 farmgate, and set beside the one Philippine backyard flock anybody has actually measured.
Four substitutions, one per sack you are standing in front of. Two of them hold at a published ceiling, one holds only if you buy it rather than dry it, and one has a number in the Philippine standard that ordinary ipil-ipil leaf misses by a factor of at least 5,100.
The comparison everyone makes runs both birds on pesos per kilo. Four in five native chicken keepers in a 584-respondent Region 1 survey never sell by the kilo at all, which is where most native-versus-broiler arithmetic quietly falls apart.
There is no such thing as the Philippine chicken price. For June 2026 there are eleven, every one correct: seven priced by the kilo from ₱117.47 to ₱343.40, and four eggs priced by the piece.
Every guide to Philippine native chicken breeds carries a table of weights. Those weights are not in any Philippine primary source. What is published is eggs, egg weight, fertility and hatchability, and this page prints the empty columns rather than filling them in.
This country publishes what a keeper sells and almost nothing a keeper buys. That asymmetry is not an oversight, and once you see the mechanism behind it you can predict which numbers exist before you go looking.
The day-old chick figure is published, wholesale, and not what a dealer will quote you for 20 sisiw. Feed, coop, vaccine and equipment have no Philippine price at all. What is computable is the shape: cost per bird falls hard from 20 to 50 and barely at all from 50 to 100.
₱150.31 and ₱118.69 are both the June 2026 Philippine broiler farmgate price. The gap is not an error, and averaging the two is.
Every wrong number this archive has published came in the same way: a primary record, restated by somebody, read at second hand. The fifth retraction broke the pattern by not being an error.
The advice a Philippine keeper finds first was written at 40 degrees north, where the year swings six hours of daylight. Manila swings one hour and forty-four minutes. Something else stopped your hens, and the order you check in should be set by how long each cause takes to come back.
Every feed number quoted for Philippine native chickens traces back to one 20-bird thesis on the Banaba strain. This page says what it measured and what it could not.
Boholano lays fewer eggs than Darag and is the only native line whose weight at a stated age is published at all. The curve stops at day 120 and drawing it further is not evidence.
Camarines lays the same 62 eggs as Boholano and has the second-lowest published fertility of the documented Philippine native lines. The published percentages do not multiply.
Forty birds at Caraga State University produced the fullest published record of any Philippine native line. It also produced two different annual egg figures, and nobody reconciled them.
Darag is the best-documented native line in the country on eggs and the least documented on meat. This page prints both halves, including the columns nobody can fill.
The brown commercial layer behind most backyard point-of-lay pullets. Its published standards are cumulative to a flock age, not eggs per year, and the difference matters.
Paraoakan is one of only two Philippine native lines with a measured adult weight in print. The same study also carries recalled figures, and the two halves must not be read the same way.
Most Philippine broiler chicks are Ross or Cobb, and the numbers everyone quotes come from a breeder booklet written for a controlled house. Here is the table and here is the gap.
A breeding programme that raises egg number can pay for it in age at maturity. ZamPen is the one Philippine native line where both halves of that trade were published.
