12 articles on breeds for Philippine backyard keepers, every peso figure sourced and dated.
Which bird to keep, and what the published growth tables actually promise. Breed guides written for controlled houses in Europe and the United States do not survive a Philippine backyard unchanged, and the gap between the table and the bakuran is the thing worth measuring.
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.
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.
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.
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.
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.
