Hens kept for eggs, where the money question is cost per egg rather than price per kilo. A layer earns over months instead of one sell day, so the figures that decide it are feed intake, lay rate and how long the flock holds up.
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.
Is the pugad in your kulungan the hottest box in the building? DA Administrative Order No. 12 files nest boxes under TEMPERATURE rather than under housing, and the standard that describes the box asks for it enclosed, curtained and draught free. On the light half, three Philippine documents set an intensity three times over and an hour target never, and the bulb that would close December costs ₱12.12 a month.
The buyer does not decide what your tray is worth. Eight weight classes, three quality grades and a 2 to 3% moisture loss in transit decide it, and all three live in one Philippine document that almost nobody selling itlog has opened.
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.
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.
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.
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.
Hy-Line and Lohmann were measured separately and land on the same feed-per-egg figure. Put it against the June 2026 farmgate and the margin on an egg is thinner than anybody tells you.
Every beginner's guide opens on how many chickens to get. That question is fifth, and it is derived: three of the four decisions above it are fixed on day 1 and cannot be managed down later, while the head count is only ever the smallest of what your floor holds, what your buyer absorbs, and what your own three quotes will fund.
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.
Bolinao is the Philippine native line with the most measured laying record. The feed conversion in it is a layer figure, and reading it as a grow-out figure is the easiest mistake here.
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.
